Abstract

Excited states of neutron-rich nucleus 82Ge were studied from the spontaneous fission of 252Cf. Eleven new transitions and seven new levels in 82Ge were identified by using X(Dy)-γ-γ and γ-γ-γ triple coincidences. Possible excited deformed rotational bands are observed, for the first time, in this nuclear region. Coexistence of the spherical ground and deformed excited shapes is proposed in 82Ge. These deformed rotational bands can be formed by two-particle, two-hole excitations with the 0+ pairing energy states of the ν9/2[404]21/2[431]2 configuration across the N=50 closed shell.
