  The problem of the near vanishing of the Gamow-Teller transition ($GT$) in
the A=14 system between the lowest $J=0^+~ T=1$ and $J=1^+~ T=0$ states is
revisited. The model space is extended from the valence space $(p^{-2})$ to the
valence space plus all 2$\hbar \omega$ excitations. The question is addressed
as to what features of the effective nucleon-nucleon interaction in the medium
are required to obtain the vanishing $GT$ strength in this extended space. It
turns out that a combination of a realistic strength of the tensor force
combined with a spin-orbit interaction which is enhanced as compared to the
free interaction yields a vanishing $GT$ strength. Such an interaction can be
derived from a microscopic meson exchange potential if the enhancement of the
small component of the Dirac spinors for the nucleons is taken into account.
