Proton states in theN = 86 nuclei147Pm and149Eu populated in the (3He,d), (α,t) and (t, α) reactions

The (3He,d) and (α, t) reactions on targets of146Nd and148Sm have been studied, using beams of 24 MeV3He and 27 MeV4He from the McMaster University tandem van de Graaff accelerator. Also the (t, α) reaction on a target of148Sm has been studied, using 17 MeV tritons from the Los Alamos Scientific Laboratory tandem accelerator. The reaction products were analyzed with magnetic spectrographs. Information on thel-values was obtained from (3He,d) …
