Parity determinations inCd105−109from linearly polarized gamma rays following (O16,xn) reactions

Abstract

The linear polarization of $\gamma$ rays from the deexcitation of Cd isotopes $A=105\mathrm{}$ through 109 following (${}_{}{}^{16}{}_{}{}^{}\mathrm{O},xn$) reactions were measured using a Ge(Li) Compton polarimeter. The linear polarizations are used with $\gamma$-ray angular distributions to make unique-parity assignments and to remove ambiguity in angular-momentum values. With these measurements it is possible to identify many states in ${}_{}{}^{105-109}{}_{}{}^{}\mathrm{Cd}$ which are similar to states in Pd nuclei that have been interpreted as having one, two, or three quasiparticles coupled to a slightly deformed rotating core.
