摘要
States in Cd-112 have been studied with the Cd-111((d) over right arrow, p) Cd-112 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 s(1/2) circle times h(11/2) two-quasineutron configuration as the dominate component of its wave function.
