Abstract

High spin states in 134 I were identified for the first time based on measurements of prompt γ rays from the spontaneous fission of 252 Cf at Gammasphere. Five excited levels with five deexciting transitions were observed. The mass number was assigned based on the intensity of transitions in the complementary Rh fragments. Angular correlations for the first two transitions in 134 I and for high spin states in 133,135,136 I were performed, but were not sufficient to firmly assign the spins and parities in 134 I.
