Comment on “Question of low-lying intruder states in8Beand neighboring nuclei”

Abstract

Calculations by Fayache et al. [Phys. Rev. C 57, 2351 (1998)] find no low-lying intruder states in ${}^{8}\mathrm{Be},$ in contrast with the situation in ${}^{10}\mathrm{Be}$ and ${}^{12}\mathrm{C}.$ It is argued that the models they used are not sufficiently realistic for their results to settle the question of whether or not such states exist in ${}^{8}\mathrm{Be}.$
