The weak fragments of the 3pl/2, 3p3/2, 2f5/2, 2f7/2 and 1i13/2 proton states of 2~ as seen in the 2~ (3He, d) reaction can be explained with the coupling of the renormalised proton states and the vibrational states of 2~The energies of the zerothorder proton shell-model states as well as the collective admixtures of the weak fragmented proton states of 2~ have been deduced from the core-particle coupling model.
