A study of the nuclear structure of 81Ge has been performed in order to better understand shell evolution in neutron-rich nuclei near the doubly magic 78Ni. The experiment was performed at the CERN ISOLDE facility in the framework of a systematic ultra-fast timing [1] investigation of neutron rich nuclei populated in the decay of Zn. The use of the ISOLDE RILIS and a cooled transfer line...

An enhanced collectivity was discovered in the N=40 Cr and Fe isotopes, but its evolution beyond N=40 and the maximum of collectivity remains unknown. The first campaign of the Shell Evolution And Search for Two plus Energies At the RIBF (SEASTAR) scientific program took place in Spring 2014 at the Radioactive Isotope Beam Factory. It focused on the first spectroscopy of the more neutron-rich...

The nuclear momentum distribution (NMD) is often quoted as being composed of two separate parts. Below the Fermi momentum (250 MeV/c) single nucleons move as independent particles in a mean field created by their mutual interactions. Above the Fermi momentum nucleons predominantly belong to short-range correlated (SRC) pairs with high relative and low center-of-mass momenta, where high and low...

Among the weak processes in nuclei, Gamow-Teller (GT) transitions caused by the στ-type interaction are very popular. They play important roles, for example, in the early stage of the core collapse of supernovae. Studies of GT strenghts B(GT) in pf-shell nuclei using (p,n) and (n,p) Charge-Exchange (CE) reactions at intermadiate energies started in the 1980s. They provided rich information on...

Gamow-teller is a weak interaction of spin-isospin type. By studying GT transitions we can obtain some information about nuclear structure as well as nuclear astrophysics. GT transitions can be studied by beta decay and charge exchange reactions. β decay has a direct access to the absolute GT transition strengths B(GT). Charge Exchange reactions are also useful to determine B(GT) strengths up...

Atomic masses of radioactive nuclides provide crucial information for a number of research topics, from nuclear structure and its manifestations across the nuclear chart, to the modelling of the r-process of nucleosynthesis. In this contribution, we will present the latest mass measurements from the precision Penning-trap mass spectrometer ISOLTRAP, located at the ISOLDE facility at CERN. The...

Energy levels and the B(E2) values of even- even 70-76Ge isotopes have been calculated through shell model calculations using the shell model code OXBASH for windows, employing the SLG model space and SLGM interaction. The energy level calculations were in good agreement with experimental data. The B(E2) values and β2, the quadrupole deformation parameter, results were consistent with the...

EXL (EXotic nuclei studied in Light-ion induced reactions at storage rings) is a project within NUSTAR at FAIR. It aims for the investigation of light-ion induced direct reactions in inverse kinematics with radioactive ions in storage rings at the future FAIR facility. One of the key interests of EXL is the investigation of reactions at very low momentum transfers where, for example, the...
