Fusion-evaporation cross sections for $^{64}\mathrm{N}\mathrm{i}+^{64}\mathrm{N}\mathrm{i}$ have been measured down to the 10 nb level. For fusion between two open-shell nuclei, this is first observation of a maximum in $S$-factor, which signals strong sub-barrier hindrance. A comparison with $^{58}\mathrm{N}\mathrm{i}+^{58}\mathrm{N}\mathrm{i}$, $^{58}\mathrm{N}\mathrm{i}+^{60}\mathrm{N}\mathrm{i}$, and $^{58}\mathrm{N}\mathrm{i}+^{64}\mathrm{N}\mathrm{i}$ systems indicates dependence...
We have identified two isomers in $^{254}\mathrm{No}$, built on two- and four-quasiparticle excitations, with quantum numbers ${K}^{\ensuremath{\pi}}={8}^{\ensuremath{-}}$ (${14}^{+}$), as well a low-energy 2-quasiparticle ${K}^{\ensuremath{\pi}}={3}^{+}$ state. The occurrence of establishes that $K$ is good number therefore the nucleus has an axial prolate shape. states probe energies proton levels govern stability superheavy nuclei, test from theory, thereby check their predictions magic gaps.
We report the first observation of two wobbling bands in $^{183}$Au, both which were interpreted as transverse (TW) band but with different behavior their energies a function spin. It increases (decreases) spin for positive (negative) parity configuration. The crucial evidence nature bands, dominance $E2$ component $\Delta I = 1$ transitions between partner is provided by simultaneous measurements directional correlation from oriented states (DCO) ratio and linear polarization $\gamma$ rays....
A high-statistics, high-resolution, complete kinematical measurement has been performed to estimate the quantitative contributions of various direct 3$\ensuremath{\alpha}$ decay mechanisms in famous Hoyle state, ${0}_{2}^{+}$ resonant excited state ${}^{12}$C at an excitation energy 7.654 MeV, using inelastic scattering 60-MeV $\ensuremath{\alpha}$ particles on ${}^{12}$C. The present observation nonzero branching ratios modes, which have extracted...
Precise estimation of the rare direct 3α decay Hoyle state 12C has been made to unveil its unusual α-cluster configurations ranging from linear chain structure diffuse Bose gas as well Einstein condensate. The present new high precision, nearly zero background experimental study with 1.6×105 events converged on upper limit for at ∼0.019% 95% confidence limit, which is more than a factor 2 lower obtained in previous studies.
Abstract Effort has been expended to assess the relative merits of undertaking further decay-data measurements main fission-product contributors decay heat neutron-irradiated fissionable fuel and related actinides by means Total Absorption Gamma-ray Spectroscopy (TAGS - sometimes abbreviated TAS) Discrete (DGS). This review carried out following similar work performed under auspices OECD/WPEC-Subgroup 25 (2005–2007) International Atomic Energy Agency (2009, 2014), various highly relevant...
Measurements of de-excitation \ensuremath{\gamma} rays in coincidence with target-like residues produced deep inelastic transfer reactions $^{238}\mathrm{U}$ on a $^{48}\mathrm{Ca}$ target at an energy near the Coulomb barrier are presented. A systematic analysis, within shell model approach, measured low-lying states odd and even neutron-rich Ca isotopes points toward possible absence predicted closure $N=34$.
Results from the gamma-ray spectroscopy of {47,48}Ar exemplifying new limits sensitivity for characterizing neutron-rich nuclei at energies around Coulomb barrier are presented. The present results, along with interacting shell model calculations, highlight role cross-shell excitations and indicate presence a nonaxial deformation in 48Ar.
The High-spin states in 195Tl, populated through the 185,187Re(13C, xn) fusion evaporation reaction at beam energy of 75 MeV, were studied using Indian National Gamma Array (INGA). More than 50 new γ transitions have been placed proposed level scheme which is extended up to excitation ≈ 5.6 MeV and spin=22.5ħ. Two pairs degenerate bands based on two different quasi-particle configurations identified this nucleus indicating first observation such an odd-A A∼190 region signify evidence...
The structure of the negative parity bands, based on $\ensuremath{\nu}{h}_{11/2}$ orbital, in $^{129}\mathrm{Ba}$ is revisited to search for wobbling mode this nucleus. Existing angular distribution/correlation and linear polarization results are indicative a large $E2$ admixture 365 keV interconnecting $\mathrm{\ensuremath{\Delta}}I=1$ $\ensuremath{\gamma}$ transition between yrast bands. This provides an indication existence Theoretical calculations performed work using quasiparticle plus...
