Abstract

A new calculation of the predominantly isoscalar PNC matrix element between the JT 0+1,0-1 (Ex8.7 MeV) states in N14 has been carried out in a (0+1+2+3+4)Latin small letter h with stroke model space with the Warburton-Brown interaction. The magnitude of the PNC matrix element of 0.22 to 0.54 eV obtained with the DDH PNC interaction is substantially suppressed compared with previous calculations in smaller model spaces but shows agreement with the preliminary Seattle experimental data. The calculated sign is opposite to that obtained experimentally, and the implications of this are discussed.
