Parity mixing in ^(21)Ne; evidence for weak neutral currents in nuclei
Abstract
The parity nonconserving circular polarization of γ-rays from the 2.789 → 0.0 MeV transition in ^(21)Ne is found to be (0.8 ± 1.4) × 10^(−3), which corresponds to a parity mixing matrix element │〈H_W〉│ = 0.009 ± 0.016 eV between the two members of the 2.8 MeV doublet. This matrix element can be combined with parity mixing matrix elements measured in ^(18)F and ^(19)F to predict isoscalar and isovector weak nucleon-nucleon coupling constants in excellent agreement with theoretical "best" values obtained in a Weinberg-Salam model calculation.
