The Gamow-Teller (GT) strength distribution in the {beta}- and {beta}+ directions starting from the ground state of 14N has been investigated. A (d,2He) experiment has been performed at KVI, Groningen with Ed=170 MeV and a (3He,t) experiment at RCNP, Osaka with E3He=420 MeV. It is found that, in both cases, the GT mechanism is populating mainly the 2+ excited states in the final nuclei, while the ground state transitions are strongly suppressed. The analysis is ongoing.
