153. Neutron Skin Effects in Mirror Energy Differences: The Case of 23Mg-23Na

Francesco Recchia (University and INFN Padova)

Oral

Energy differences between analogue states in the T=1/2 $^{23}$Mg-$^{23}$Na mirror nuclei have been measured along the rotational yrast bands with the EXOGAM + Neutron Wall + DIAMANT setup at GANIL. The nuclei of interest have been populated via the $^{12}$C+$^{16}$O fusion evaporation reaction.
This allows us to search for effects arising from isospin-symmetry breaking interactions (ISB)...

14. Discovery of collective states in the heavy $^{208}$Pb nucleus by complete spectroscopy

Oral

Complete spectroscopy for a certain nucleus means that up to a given
excitation energy for each state, spin and parity is determined by
experiment and the composition is described by some theoretical model.
Among heavy nuclei the goal to reach complete spectroscopy is
approached only for $^{208}$Pb.

Knowledge of nuclear states in $^{208}$Pb is gained since 1899. Since
the 1990s the...

179. High-spin structure and isomers near closed shell nuclei using INGA

Prof. Rudrajyoti Palit (TIFR)

Invited

Spectroscopy of the high spin states and isomers in nuclei near closed shell remain a subject of interest to study the predictions of shell model calculation based on effective interactions as well as emergence of collectivity at high spin. Some of the recent results for nuclei near N=50 and 82 shell gaps will be presented which provide interesting insight about the novel excitation modes of...
