Abstract

Proton states in 121,123,125,127,129,131I were investigated by means of Te(α, t)I and Te(3He, d)I reactions at 36 MeV bombarding energy using a Q3D magnetic spectrograph. Angular distributions were measured for transitions to 121I. From ratios of cross sections of transitions in the reactions (3He, d) and (α, t) to final states in 125–131I, the transfered orbital angular momenta and relative spectroscopy factors are extracted. New levels are observed including 72+ and 112 single-particle strength fragments. The results are interpreted using the three-particle-cluster — phonon coupling model.
