Single nucleon pickup reactions were performed with a 18.1 MeV/nucleon (14)O beam on deuterium target. Within the coupled reaction channel framework, measured cross sections compared to theoretical predictions and analyzed using both phenomenological microscopic overlap functions. The missing strength due correlations does not show significant dependence separation energy asymmetry over wide range of 37 MeV, in contrast removal data within sudden-eikonal formalism.
An excited state in the proton-rich unbound nucleus $^{12}\mathrm{O}$ was identified at 1.8(4) MeV via missing-mass spectroscopy with $^{14}\mathrm{O}(p,t)$ reaction $51\text{ }\text{ }A\mathrm{MeV}$. The spin-parity of determined to be ${0}^{+}$ or ${2}^{+}$ by comparing measured differential cross sections distorted-wave calculations. lowered location indicates breakdown major shell closure $Z=8$ near proton drip line. This demonstrates persistence mirror symmetry disappearance magic...
The N=48 Ge80 nucleus is studied by means of β-delayed electron-conversion spectroscopy at ALTO. radioactive Ga80 beam produced through the isotope separation on line photofission technique and collected a movable tape for measurement γ e− emission following β decay. An electric monopole E0 transition, which points to 639(1) keV intruder 02+ state, observed first time. This new state lower than 21+ level in Ge80, provides evidence shape coexistence close one most neutron-rich doubly magic...
Energies and spectroscopic factors of the first $7/2^-$, $3/2^-$, $1/2^-$ $5/2^-$ states in $^{35}$Si$_{21}$ nucleus were determined by means (d,p) transfer reaction inverse kinematics at GANIL using MUST2 EXOGAM detectors. By comparing information on $^{35}$Si $^{37}$S isotones, a reduction $p_{3/2} - p_{1/2}$ spin-orbit splitting about 25% is proposed, while $f_{7/2} -f_{5/2}$ seems to remain constant. These features, derived after having unfolded nuclear correlations shell model...
The quenching of the $N=20$ shell gap in neutron-rich nuclei is investigated by studying single-particle structure ${}^{27}$Ne via neutron transfer using a ${}^{26}$Ne beam. Two low-lying negative-parity intruder states have been observed, lowest which identified as ${J}^{\ensuremath{\pi}}=3/{2}^{\ensuremath{-}}$, confirming earlier speculations. A level 7/2${}^{\ensuremath{-}}$ observed higher energy than 3/2${}^{\ensuremath{-}}$, contrary to ordering at $\ensuremath{\beta}$-stability and...
The last proton bound calcium isotope $^{35}\mathrm{Ca}$ has been studied for the first time, using $^{37}\mathrm{Ca}(p,t)^{35}\mathrm{Ca}$ two neutron transfer reaction. radioactive $^{37}\mathrm{Ca}$ nuclei, produced by LISE spectrometer at GANIL, interacted with protons of liquid hydrogen target CRYPTA, to produce tritons $t$ that were detected in MUST2 detector array, coincidence heavy residues Ca or Ar. atomic mass and energy its $3/{2}^{+}$ state are reported. A large $N=16$ gap...
The spectroscopy of O21 has been investigated using a radioactive O20 beam and the (d,p) reaction in inverse kinematics. ground first excited states have determined to be Jπ=5/2+ 1/2+, respectively. Two neutron unbound were observed at excitation energies 4.77(10) 6.17(11) MeV. spectroscopic factor deduced for lower these, interpreted as 3/2+ level, reveals relatively pure (60%) 0d3/2 single-particle configuration, good agreement with shell-model calculations that predict O26 unbound. large...
The ${}^{8}$He($d,p$) reaction was studied in inverse kinematics at 15.4$A$ MeV using the MUST2 Si-CsI array order to shed light on level structure of ${}^{9}$He. well known ${}^{16}$O($d,p$)${}^{17}$O reaction, performed here reverse kinematics, used as a test validate experimental methods. ${}^{9}$He missing mass spectrum deduced from kinetic energies and emission angles recoiling protons. Several structures were observed above neutron-emission threshold angular distributions deduce...
Detailed spectroscopy of the neutron-deficient nucleus $^{36}$Ca was obtained up to 9 MeV using $^{37}$Ca($p$,$d$)$^{36}$Ca and $^{38}$Ca($p$,$t$)$^{36}$Ca transfer reactions. The radioactive nuclei, produced by LISE spectrometer at GANIL, interacted with protons liquid Hydrogen target CRYPTA, produce light ejectiles (the deuteron $d$ or triton $t$) that were detected in MUST2 detector array, coincidence heavy residues %identified a zero degree detection system. %States have been measured...
The excitation energy spectra of the residual nucleus 207Tl have been investigated up to 14 MeV using (d, 3He) reaction at 108 MeV. New high-lying states are observed for first time 8.3 MeV, in addition five known low-lying levels. Beyond 7.13 energy, weaker structures riding over a wide asymmetric bump. DWBA analysis angular distributions has allowed l attributions and determination valence inner-hole spectroscopic factors. It is found that levels 1.33, 1.67 3.47 exhaust respectively about...
The N=52 Ga83 β decay was studied at ALTO. radioactive 83Ga beam produced through the ISOL photofission technique and collected on a movable tape for measurement of γ-ray emission following decay. While β-delayed neutron has been measured to be 56–85% path, in this experiment an unexpected high-energy 5–9 MeV yield 16(4)% observed, coming from states several MeVs above separation threshold. This result is compared with cutting-edge QRPA calculations, which show that when neutrons deeply...
Laetiporus sulphureus was investigated for volatile compounds by GC/MS. Twentysix components were identified with major constituents being (Z)-3-methylcinnamaldehyde (27.5%), 2-phenylethanol (6.4%), benzaldehyde (4.0%) and N-phenylethylformamide (3.8%). Odorous aromatic derivatives represented 11.5% of the fraction. Observed sulphur contribute probably to disagreeable odour L. developed in maturation process.

Neutron hole states were investigated in the $^{207,206,205}\mathrm{Pb}$ isotopes up to 25 MeV excitation energy using ($^{3}\mathrm{He}$,$\ensuremath{\alpha}$) reaction at 100 incident with keV resolution. Above well-matched low-lying levels corresponding high angular momentum transfers, new peaks are identified. In addition, three gross structures, riding on a continuous background, observed each of isotopes, some fine structures showing 10 energy. For $^{207}\mathrm{Pb}$, distributions...
The unbound 12O nucleus was studied via the two-neutron transfer (p,t) reaction in inverse kinematics using a radioactive 14O beam at 51 MeV/u. Excitation energy spectra and differential cross sections were deduced by missing mass method MUST2 telescopes. We achieved much higher statistics compared to previous experiments of 12O, which allowed accurate determination resonance unambiguous spin parity assignment. previously reported same confirmed an excitation 1.62±0.03(stat.)±0.10(syst.)....
Strong transitions to high-lying proton states are observed for the first time in study of ($\ensuremath{\alpha}, t$) and ($^{3}\mathrm{He}$, $d$) reactions on $^{144}\mathrm{Sm}$ at 80- 240-MeV incident energy, respectively. The excitation energies, angular distributions, strengths these suggest that they arise from stripping high-spin outer subshells, e.g., $1{h}_{\frac{9}{2}}$ $1{i}_{\frac{13}{2}}$.
