It is shown that four parameters Bα, linearly related to the usual form factors Aα(q2), are especially convenient for discussing the experiments because the cross section is proportional to (Bα)2 and the polarization of the recoil nucleon is given by l→′= 2B4(B1i→2+B2i→2+B3i→3) (Bα)2. Here i→1, i→2, and i→3 are unit vectors in the directions of p→′, k→×p→′, and i→1×i→2, where p→′ is the momentum of the outgoing nucleon and k→ that of the incident neutrino. A discussion of some possible experiments is given, as suggested by this parametrization.
