Decay modes of ${}^{10}$C nuclei unbound state

Abstract

Unbound states of ${}^{10}$C nuclei produced as quasi-projectiles in ${}^{12}$C+${}^{24}$Mg collisions at E/A = 53 and 95 MeV are studied with the Indra detector array. Multi-particle correlation function analyses provide experimental evidence of sequential de-excitation mechanisms through the production of intermediate ${}^9$B, ${}^6$Be and ${}^8$Be unbound nuclei. The relative contributions of different decay sequences to the total decay width of the explored states is estimated semi-quantitatively. The obtained results show that heavy-ion collisions can be used as a tool to access spectroscopic information about exotic nuclei.
