Query: New calculations of the PNC Matrix Element for the $J^{\pi}T$
  0$^{+}1,0^{-}1$ doublet in $^{14}$N   A new calculation of the predominantly isoscalar PNC matrix element between
the $J^{\pi}T$ $0^{+}1,0^{-}1$ (E$_{x} \approx$ 8.7 MeV) states in $^{14}$N has
been carried out in a (0+1+2+3+4)$\hbar \omega$ model space with the
Warburton-Brown interaction. The magnitude of the PNC matrix element of 0.22 to
0.34 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.
