Abstract

An experimental approach aimed at reducing the uncertainties in astrophysical rapid proton capture (rp) process calculations due to nuclear data was presented. The approach utilized neutron removal from a radioactive ion beam in order to populate the nuclear states of interest. The excited states were deduced by the γ decay spectra measured in a semiconductor Ge-detector array. The ability of the process to measure the key properties of almost all interesting nuclei on the rp process path was demonstrated.
