127. Building a coherent physics picture around N=50 towards 78Ni

Andrea Gottardo (LNL)

Invited

The N=50 shell closure above $^{78}$Ni has been the subject of intense experimental efforts. While an initial spectroscopy of $^{78}$Ni itself has been achieved, the rich phenomenology around the neutron shell closure still lacks a comprehensive picture. The parabolic behaviour of the N=50 gap, decreasing from Z=40 to Z=32 and the re-increasing towards Z=30 is not well understood, also in...

110. In Flight and $\beta$-delayed $\gamma$-spectroscopy in the vicinity of $^{78}$Ni with AGATA at GANIL and BEDO at ALTO.

Oral

While the $N=50$ shell-gap evolution towards $^{78}$Ni is presently in the focus of nuclear structure research, experimental information on the neutron effective single particle energy (ESPE) sequence above the $^{78}$Ni core remain scarce. Direct nucleon exchange reactions are indeed difficult with presently available post-accelerated radioactive ion beams (especially for high orbital...

70. Recent applications of the subtracted second random-phase approximation

Danilo Gambacurta (ELI-NP)

Oral

The Second Random Phase Approximation (SRPA) is a natural extension of Random Phase Approximation obtained by introducing more general excitation operators where two particle-two hole configurations, in addition to the one particle-one hole ones, are considered.
Only in the last years,large-scale SRPA calculations, without usually employed approximations have been performed [1,2].
The SRPA...

146. Structural investigation of neutron deficient Pt isotopes: the case of 178Pt

Christoph Fransen (Institut für Kernphysik, Universität zu Köln)

Oral

Lifetime measurements with the recoil distance Doppler-shift technique
have been performed to determine yrast E2 transition strengths in 178Pt.
The experimental data are related to those on neighboring Pt isotopes,
especially recent data on 180Pt, and compared to calculations within the
interacting boson model and a Hartree-Fock Bogoliubov approach. These
models predict prolate deformed...
