Title: Neutral current effects in {sup 16}O

Abstract

The {gamma}-circular polarizations (P{sub {gamma}}) and asymmetries (A{sub {gamma}}) of several parity forbidden {gamma} transitions in {sup 16}O{sup *} have been investigated within an effective operator approach. Considering various strong and weak interaction models, the maximum theoretical value among the circular polarizations has been found to be 1.85x10{sup -3} which corresponds to the 4.15 MeV {gamma} ray (2{sup +}T=0; E{sub x}=13.02 MeV{yields}2{sup -}T=0; E{sub x}=8.87 MeV) in {sup 16}O{sup *}. The isovector component of the parity nonconserving matrix element dominates the mixing of the parity doublet (2{sup -}T=1; E{sub x}=12.9686 MeV-2{sup +}T=0; E{sub x}=13.02 MeV) in {sup 16}O{sup *}.
