摘要：

We investigate the nucleon to Delta(1232) vector and axial vector amplitudes in the nonrelativistic quark model of the Isgur-Karl variety. A particular interest is to investigate the SU(6) symmetry breaking, due to color hyperfine interaction. We compare the theoretical estimates to recent experimental investigation of the Adler amplitudes by neutrino scattering.
