Proton-hole induced bands in odd-odd /sup 118,120/Sb

Journal Article · · Phys. Rev. C; (United States)
Negative parity ..delta..J = 1 bands were observed in /sup 118,120/Sb with (/sup 7/Li,3n..gamma..) and (/sup 11/B,3n..gamma..) reactions. Bandhead and level spacing properties are consistent with the g/sub 9/2/ proton-hole collectivity and a decoupled h/sub 11/2/ neutron. These bands decay to the low-lying (..pi..d/sub 5/2/,..nu..h/sub 11/2/)/sup 8 -/ isomers via several high-spin states, one of which, 7/sup(/sup +/) in /sup 118/Sb, had a measured t/sub 1/2/ = 22.4 +- 0.5 ns. Comparisons to ..pi..g/sub 9/2/ /sup -1/ ..delta..J = 1 bands in odd-mass Sb nuclides are made.
