Study of neutron-rich A$\sim $30 nuclei in multi-nucleon transfer reactions

ORAL

Abstract

The structure of neutron-rich s-d-f shell nuclei in the mass A$\sim $30 region has been investigated through multi-nucleon transfer in the $^{208}$Pb($^{36}$S,X$\gamma )$ reaction at 230 MeV. Gamma-radiation from the reactions was detected using GAMMASPHERE [1]. Mass identification of the target-like and projectile-like products as well as an event-by-event Doppler-shift correction was possible by utilizing the excellent spatial and timing resolution of the heavy-ion counter CHICO [2]. The level schemes of several nuclei are significantly expanded. The measurements are compared to shell-model calculations to test the current understanding and to provide new information on the neutron-proton interaction in neutron-rich s-d-f shell nuclei.
