The low-spin structure of the semimagic ^{64}Ni nucleus has been considerably expanded: combining four experiments, several 0^{+} and 2^{+} excited states were identified below 4.5 MeV, their properties established. Monte Carlo shell model accounts for results unveils an unexpectedly complex landscape coexisting shapes: a prolate excitation is located at surprisingly high energy (3463 keV), with collective state 286 keV above it, first such observation in Ni isotopes. evolution minimum...
Polonium isotopes having two protons above the shell closure at Z=82 show a wide variety of low-lying, high-spin isomeric states across whole chain. The structure neutron-deficient up to ^{210}Po (N=126) is well established as they are easily produced through various methods. However, there not much information available for neutron-rich counterparts which only selective techniques can be used their production. We report on first fast-timing measurements yrast 8^{+} level in ^{214,216,218}Po...

Abstract We have extracted the nuclear level density of 128Te from a (p,p'γ) scattering experiment using large-volume LaBr3:Ce and CeBr3 detectors ELI-NP at 9 MV Tandem facilities IFIN-HH. The decay data were normalised photonuclear data, resulting in densities without intrinsic model dependencies constant temperature or Fermi gas models. deduced follows between expectations these two models, but we observe clear divergence microscopic based on Skyrme force.
