Abstract

High-spin states in odd-odd ¹⁶⁴Lu have been studied using ¹⁹F and ²³Na induced fusion-evaporation reactions. Three strongly coupled rotational bands have been established and three decoupled bands were tentatively assigned to ¹⁶⁴Lu. The band crossing frequencies, energy signature splittings, and relative transition probabilities were deduced from experimental data and compared with neighboring even-even and odd-A nuclei. An anomalously large band crossing frequency was observed in the excited band, and a pronounced signature inversion was observed in the yrast band of ¹⁶⁴Lu. These anomalies may be associated with residual neutron-proton interactions.
