The low-lying, low-spin levels of $^{76}\mathrm{Ge}$ were studied with the $(n,{n}^{\ensuremath{'}}\ensuremath{\gamma})$ reaction. Gamma-ray excitation function measurements performed at incident neutron energies from 1.6 to 3.7 MeV, and $\ensuremath{\gamma}$-ray angular distributions measured 3.0 3.5 MeV. From these measurements, level spins, lifetimes, intensities, multipole mixing ratios determined. No evidence for a number previously placed was found. Below 3.3 many new identified,...

Excited states in $^{106}\mathrm{Pd}$ were studied with the $(n,{n}^{\ensuremath{'}}\ensuremath{\gamma})$ reaction, and comprehensive information for excitations spin $\ensuremath{\le}6\phantom{\rule{0.16em}{0ex}}\ensuremath{\hbar}$ was obtained. The data include level lifetimes femtosecond regime, spins parities, transition multipolarities, multipole mixing ratios, which allow determination of reduced probabilities. $E2$ decay strength to low-lying is mapped up $\ensuremath{\approx}2.4$ MeV...

Inelastic neutron scattering was used to study the low-lying nuclear structure of $^{132}$Xe. A comprehensive level scheme is presented, as well new lifetimes, multipole mixing ratios, branching and transition probabilities. Comparisons these data previously measured $E2$ strengths $g$ factors are made with shell-model calculations for $^{132,134,136}$Xe explore emergence collectivity in Xe isotopes $N$ < 82 near closed shell.

There have been great improvements in the predictions of nuclear masses, yet it is difficult to exactly reproduce measured mass. It has suggested that cause such discrepancies due negligence many-body effects available theoretical models. The errors prediction mass show residual correlations missing physics In present Letter we tried learn by using neural networks. We used a network architecture which adaptively learns linear and nonlinear between data different fidelity. finite range...
