92. EXOTIC NUCLEI: THE $^{78}$Ni REGION (ZOOM)

Frédéric NOWACKI (Institut Pluridisciplinaire Hubert Curien)

01/08/2023, 09:00

Invited talk

In this contribution,
I will expose microscopic nuclear structure calculations for exotic nuclei far from stabilitity in the vicinity of $^{78}$Ni, in a key region needed for understanding nucleosynthesis paths of gold and some of the most heavy elements.
Our recent algebraic Nilsson SU3 self-consistent model[1] will be used to describe the intruder relative evolution in the vicinity of...

83. Single-particle structure of neutron-rich copper

Serge Franchoo (IJC)

Invited talk

The neutron-rich copper isotopes are an ideal laboratory to investigate nuclear structure at intermediate mass as in principle they allow to follow the movement of a single proton around a core of magic nickel. In this talk I shall briefly present the experimental data gathered from $\beta$-decay, laser spectroscopy, Coulomb excitation and transfer reactions, after which I shall focus on the...

94. Nuclear Structure in neutron-rich Ni region

Invited talk

We have studied medium-mass nuclei of various regions by Monte Carlo shell model (MCSM) calculations. Our MCSM calculations for Ni isotopes reproduce well their properties such as levels and transitions. Shape coexistence of nuclei around 68Ni is predicted by the calculations and explained by considering change of shell structure. Neutron-rich nuclei around N=50 are calculated by using...

43. 78Ni: Doubly magic nuclei at the onset of deformation

Ryo Taniuchi (Department of Physics, University of York)

Invited talk

78Ni, which has 28 protons (Z = 28) and 50 neutrons (N = 50), 14 additional neutrons to the last stable nickel isotope 64Ni, is one of the most intriguing isotopes in the chart of nuclei. It is the most neutron-rich, exotic “doubly magic” nucleus that can be produced at present state-of-the-art facilities. The excited states of 78Ni have been investigated at the Radioactive Isotope Beam...

18. Nuclear structure of 76Ni from the (p,2p) reaction

Invited talk

The nuclear structure of the 76Ni nucleus was investigated by (p,2p) reaction using a NaI(Tl) array to detect the deexciting prompt γ rays. A new transition with an energy of 2227 keV was identified by γγ and γγγ coincidences. According to these coincidence spectra, the observed transition connects a new state at 4147 keV and the previously known 4+1 state at 1920 keV. Two weaker transitions...
