Description
Deuteron evaporation was observed from the $N=Z$ compound nuclei $^{52}$Fe$^\star$, $^{56}$Ni$^\star$, and $^{64}$Ge$^\star$ in an experiment conducted at Argonne National Laboratory, USA. The experiment included a novel combination of two highly pixelated double-sided Si-strip detectors inside the Microball charged-particle detection array, allowing for unequivocal discrimination of evaporated deuterons from protons and $\alpha$ particles. In conjunction with the Gammasphere array, Neutron Shell, and additional ancillary detectors, decay paths into various residual nuclei were investigated. The study provides insights into the competition of deuteron vs.~proton-neutron evaporation as a function of available excitation energy and populated angular momentum. Results are interpreted using a statistical evaporation formalism for multiple subsequent particle emissions. Findings from the comparison of single-nucleon and deuteron evaporation will be presented in the talk.
