Gamma ray studies of neutron-richsdfshell nuclei produced in heavy ion collisions

Reanalysis of ichproductsofbinaryreactio nsof}}³⁴$S, $³⁶S$, and $³⁷Cl$ beams on $¹⁶⁰Gd$ targets. Gates set on known amma$raysinA~160 products selected individual react ion channels and identified coincident ammaraysin$A{~}36 partner products. Transfers of protons from projectile to target and of neutrons from target to projectile were generally favored, leading to excited neutron-rich light nuclei, including some difficult to reach by other means.

In two N=19 nuclei, $³³Si$ and $³⁴P$, the two N=22 nuclei, $³⁸S$ and $³⁹Cl$, previously unknown yrast states were identified.
