Abstract

The parity-nonconserving circular polarization of

γ

rays from the 2.789 → 0.0 MeV transition in

{}^{21}{Ne}

is found to be (-9 ± 51) ×

10^{- 4}

, which corresponds to a parity-mixing matrix element

| 〈 H_{PNC} 〉 | = 0.009 \pm 0.054

eV between the 2.80-MeV,

J^{π} = {\frac{1}{2}}^{\pm}

levels. This value is considerably smaller than the measured parity mixing in the

J = \frac{1}{2}

doublet in

{}^{19}F

.
