51. Evolution of the shell structure in medium mass nuclei: search of the neutron 2d5/2 orbital in 69Ni

The Harmonic Oscillator closed shell at N=40 in 68Ni is weak and loses its strength at two proton-holes distance. This was manifested in 64,66Fe and 60,62Cr nuclei by the deformation of the low-lying states. Calculations performed in this mass region predict a new island of inversion at N=40 similar to the one discovered at N=20. Using a large valence neutron space, the neutron 1g9/2-2d5/2 gap...

108. Proton-Neutron interaction around N=40 studied at ISOLDE

Talk

One of the main goals of modern nuclear structure research is to identify changes in the mean field or residual interaction when going towards exotic systems. To track such changes, different observables are available for the experimentalist, like effective single particle energies for odd nuclei or values for the electric quadrupole transition strength in even-even nuclei. In this talk we...

17. Test of the asymmetry of reduction factors with one nucleon transfer reaction on 14O

Talk

Nucleon transfer reactions have been for years a powerful tool to investigate the filling of orbitals issued from the nuclear shell model. Even for the most stable nuclei, spectroscopic factors deviate from unity. It is understood as the result of short or long-range correlations. In the case of exotic nuclei, the variation of spectroscopic factors with the difference in separation energy ΔS =...

52. Asymptotic normalization coefficients of mirror states in 21Al

Talk

The structure of nuclei at and beyond the proton-drip line is important in the understanding of the rapid proton capture nucleosynthethic process (rp process). Knowledge of the nuclear properties in the light proton drip line region Z~13 are key inputs to network calculations of the rp-path. However, little spectroscopic information is known about the structure of 21Al which is proton unbound....
