We calculate n alpha phase-shifts and scattering observables in theresonating-group method, using the nuclear-matter G-matrix of an SU_6quark-model NN interaction. The G-matrix is generated in the recentenergy-independent procedure of the quark-model NN interaction with thecontinuous prescription for intermediate spectra, by assuming an appropriateFermi momentum k_F=1.2 fm^-1. The n alpha RGM interaction kernels are evaluatedwith explicit treatments of the nonlocality and momentum dependence ofpartial-wave G-matrix components. The momentum dependence of the G-matrixcomponents is different for each of the nucleon-exchange and interaction types.Without introducing any artificial parameters except for k_F, the central andspin-orbit components of the n alpha Born kernel are found to have reasonablestrengths under the assumption of a rigid translationally invariant shell-modelwave function of the alpha-cluster. The characteristic behaviors of threedifferent exchange terms, corresponding to knockout, heavy-particle pickup andnucleon-rearrangement processes, are essentially the same between the case ofprevious local effective NN forces and the case of nonlocal G-matrix NNinteractions.
