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