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