Recoil distance lifetimes of rotational states in /sup 236/U

Journal Article · · Phys. Rev., C; (United States)
Half-lives for members of the /sup 236/U ground-state rotational band have been measured by the recoil-distance method following Coulomb excitation with /sup 40/Ar/sup 8 +/ projectiles. The B (E2, I..-->..I-2) values in units of e/sup 2/ b/sup 2/ determined from the half-lives of the 4/sup +/, 6/sup +/, 8/sup +/, 10/sup +/, and 12/sup +/ states are 3.03+-0.20, 3.28+-0.19, 3.42+-0.28, 3.11+-0.30, and 3.34/sup +2/./sup 23//sub em-dash//sub 0//sub .9//sub 5/, respectively. Transition quadrupole moments Q/sub 20/(I/subi/..-->..I/subf/) deduced from the lifetimes are constant within experimental error and thus support the characterization of /sup 236/U as a good rotor to spin 12/sup +/.
