DOI: 10.1103/physrevc.100.024301
Abstract: Lifetimes of $2^+_1$ and $4^+_1$ states, as well as some negative-parity and non-yrast states, in $^{188-200}$Hg were measured using $\gamma-\gamma$ electronic fast timing techniques with the LaBr$_3$(Ce) detector array of the GRIFFIN spectrometer. The excited… read more here.

DOI: 10.1103/physrevlett.125.102502
Abstract: 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, and their properties established. The Monte Carlo shell model accounts for… read more here.

DOI: 10.1142/s0218301319500861
Abstract: The Po isotopes show the presence of coexisting structures having different deformations with increasing neutron number within the macroscopic–microscopic Nilsson–Strutinsky formalism. The model is based on the Lublin Strasbourg Drop (LSD) method for the macroscopic… read more here.
