Abstract

We have studied the properties of low‐lying levels in 7He using the d(6He,p)7He reaction. Recent measurements of 8He breakup and the p(8He,d)7He reaction present conflicting results on 7He first excited state A broad resonance observed in the present work at EX = 2.2−0.1+0.2 MeV is identified with the expected 1/2− spin‐orbit partner to the 7He ground state. No evidence is seen of a lower first‐excited state that was recently reported.
