Abstract

Six rotational bands have been established in Sm-136 following heavy-ion induced reactions carried out at the Nuclear Structure Facility, Daresbury. The yrast band has been observed up to I(pi) = (24+) and undergoes three band-crossings. A band was observed built on the low-lying 2+ gamma-vibrational state, in addition to two negative parity sidebands built on two-quasiproton excitations. A dipole band showing the characteristics of collective oblate rotation was also established. The results am discussed in terms of total Routhian surface and cranked Woods-Saxon model calculations.
