Quadrupole moment of the 8/sup -/ isomer in /sup 112/Sb

Journal Article · · Phys. Rev. C; (United States)
The quadrupole interaction of the 8/sup -/ isomeric state (T/sub 1/2/ = 536 ns) in /sup 112/Sb has been measured using the time differential perturbed angular distribution method. The linear momentum transfer from the /sup 103/Rh(/sup 12/C, 3n) reaction recoiled the isomeric nuclei into single crystals of Sb and Sn and a polycrystalline In foil. From the quadrupole coupling constant for the 8/sup -/ state of /sup 112/Sb in Sb, the quadrupole moment was obtained relative to the moment of the stable ground state of /sup 121/Sb: Vertical BarQ(/sup 112/Sb,8/sup -/)/Q(/sup 121/Sb,(5/2)/sup +/)Vertical Bar = 1.958(10). The value is in accordance with the description of the isomer as an odd proton coupled to a neutron-excited Sn core. In addition, the measured coupling constants in Sn and In allow the determination of the quadrupole moments of isomers in /sup 120,122/Sb and /sup 115/Sb.
