The spin-orbit splitting between neutron 1p orbitals at 33Si has been deduced using the single-neutron-adding (d,p) reaction in inverse kinematics with a beam of 32Si, long-lived radioisotope. Reaction products were analyzed by newly implemented SOLARIS spectrometer reaccelerated-beam facility National Superconducting Cyclotron Laboratory. measurements show reasonable agreement shell-model calculations that incorporate modern cross-shell interactions, but they contradict prediction proton...
The nuclei below lead but with more than 126 neutrons are crucial to an understanding of the astrophysical r process in producing heavier A∼190. Despite their importance, structure and properties these remain experimentally untested as they difficult produce nuclear reactions stable beams. In a first exploration shell this region, neutron excitations ^{207}Hg have been probed using neutron-adding (d,p) reaction inverse kinematics. radioactive beam ^{206}Hg was delivered new ISOLDE Solenoidal...
Absolute cross sections for the addition of s- and d-wave neutrons to ^{14}C ^{14}N have been determined simultaneously via (d,p) reaction at 10 MeV/u. The difference between neutron proton separation energies, ΔS, is around -20 MeV ^{14}C+n system +8 ^{14}N+n. population 1s_{1/2} 0d_{5/2} orbitals both systems reduced by a factor approximately 0.5 compared with independent single-particle model, or about 0.6 when shell model. This finding strongly contrasts results deduced from...
The single-particle properties of $^{29}\mathrm{Mg}$ have been investigated via a measurement the $^{28}\mathrm{Mg}(d,p)^{29}\mathrm{Mg}$ reaction, in inverse kinematics, using ISOLDE Solenoidal Spectrometer. negative-parity intruder states from $fp$ shell identified and used to benchmark modern shell-model calculations. systematic data on centroids along $N=17$ isotones show good agreement with predictions describing observed trends stability toward $^{25}\mathrm{O}$. However, there is also...
The pairing properties of the neutrinoless double-$\beta$ decay candidate $^{116}$Cd have been investigated. Measurements two-neutron removal reactions on isotopes $^{114,116}$Cd made in order to identify 0$^+$ strength residual nuclei up $\approx$3 MeV. No significant $L=0$ has found excited states indicating that Bardeen-Cooper-Schrieffer (BCS) approximation is a reasonable basis describe neutrons ground state. This avoids complications calculations matrix elements use quasiparticle...
Nucleon-transfer sum rules have been assessed via a consistent reanalysis of cross-section data from neutron-adding ($d,p$) and -removing ($d,t$) reactions on well-deformed isotopes Gd, Dy, Er, Yb, W, with $92\ensuremath{\le}N\ensuremath{\le}108$, studied at the Niels Bohr Institute in 1960s 1970s. These are complemented by new measurements cross sections using ($d,p$), ($d,t$), ($p,d$) subset these nuclei. The rules, defined Nilsson-model framework, remarkably consistent. A single overall...
The spin-orbit splitting between neutron 1$p$ orbitals at $^{33}$Si has been deduced using the single-neutron-adding ($d$,$p$) reaction in inverse kinematics with a beam of $^{32}$Si, long-lived radioisotope. Reaction products were analyzed by newly implemented SOLARIS spectrometer reaccelerated-beam facility National Superconducting Cyclotron Laboratory. measurements show reasonable agreement shell-model calculations that incorporate modern cross-shell interactions, but they contradict...
The 7 Be( d , p) 8 Be ∗ reaction was measured in inverse kinematics at a beam energy of 11 MeV/u using the ISOLDE Solenoidal Spectrometer, order to identify and characterise high-excitation states Be. spin-parities many 16−20 MeV region can be explained as being particle-hole excitations within two-centre shell model. present experiment aims elucidate spin parities higher excited states, > 20 MeV, assess their candidacy rotational aforementioned particlehole states. intensity this...
