Abstract

The neutron-deficient nucleus ¹²³La was studied via the ⁹²Mo(⁴⁰Ca,2ap) reaction at a beam energy of 184 MeV. Previously known bands were extended to a much higher spin, and in two cases the structures are now observed near 40ℏ. In addition, three new sequences were identified and linked into previously known bands. The lowest (π,α)=(+,-1/2) structure displays characteristics similar to those of analogous bands in ^127,129La, which have been proposed as examples of smooth band termination. Cranked Nilsson-Strutinsky calculations were compared with the experimental data in ¹²³La to determine whether this band is approaching a terminating state as well.
