Abstract

States in Cd112 have been studied with the Cd111(d,p)Cd12 reaction using 22 MeV polarized deuterons. The protons from the reaction were momentum analyzed with a Q3D magnetic spectrograph, and spectra have been recorded with a position-sensitive detector located on the focal plane. Angular distributions of cross sections and analyzing powers have been constructed for the low-lying negative-parity states observed, including the 3,4, and 5 members of the previously assigned quadrupole-octupole quintuplet. The 5 member at 2373-keV possess the second largest spectroscopic strength observed, and is reassigned as having the s12h112 two-quasineutron configuration as the dominate component of its wave function.
