Abstract

Excited states in the neutron-deficient nucleus ${}^{29}S$ were populated in one-neutron knockout and several-nucleon removal reactions and studied using in-beam $γ$ -ray spectroscopy. New excited states and $γ$ -ray transitions were established using the Segmented Germanium Array SeGA and the $γ$ -ray tracking array GRETINA. The new transitions observed in the highly dissipative tail of the parallel momentum distribution from one-nucleon knockout and in five- and nine-nucleon removal reactions were utilized to calculate mirror energy differences with ${}^{29}{Al}$ . Highly dissipative reactions further prove to be a valuable tool in populating excited states typically inaccessible in direct reactions. The relative populations of the states in ${}^{29}S$ from the several-nucleon removal reactions were found to be consistent, suggesting for the first time that five-nucleon removal behaves predominately like statistical fragmentation.
