Abstract
High spin states of 140Sm have been populated using the 116Cd (28Si, 4n) 140Sm heavy ion fusion evaporation reaction. The previously reported level scheme has been considerably modified and extended. Spin and parity assignments have been made using the DCO and IPDCO methods. Multi-quasiparticle configurations have been assigned to various ΔI = 1 and ΔI = 2 bands based on systematic. A band structure similar to 140Sm has been found in 136Ce. So, the alignments in both the nuclei are compared for various band structures having similar band head spin. This helps in assigning the configuration to various band structures. Level structures have been discussed in the framework of the tilted axis cranking model. Lifetimes of states have been measured using the DSAM method.
