Studies of yrast and continuum states in A = 140 to 160 nuclei. Progress report, January 1, 1981-December 31, 1981
Nuclear structure studies in the A approx. 150 region by ..gamma..-ray spectroscopy following heavy ion induced reactions are summarized. Yrast states of N = 82 nuclei close to the proton drip line have been identified as rather pure (..pi..h/sub 11/2)/sup n/ excitations of seniority 2 and 3. The high-spin level structure of /sup 154/Dy has been determined through the /sup 124/Sn(/sup 34/S,4n..gamma..) reaction. Both the structure and the level lifetimes indicate a transition at I approx. 32 from collective to few-particle character, with possible shape changes from prolate-to-triaxial-to-oblate.
