Abstract

The two signatures of a band built on a πh112 shell model state have been established to high spin (Iπ = 652) in 165Lu. An observed second band crossing at ℏ ω ∼ 0.40 MeV is interpreted as the alignment of a second pair of i132 neutrons. M1 transitions are observed through both crossing and the data utilized in connection with the observed signature splitting of energies and alignments to interpret the measured values of B(M1, I → I − 1)Q20. Alignment effects and shape changes are discussed.
