Abstract
We analyze the and reactions within the four- and five-body continuum discretized coupled channel method. The nucleus is described by a configuration in hyperspherical coordinates. This description reproduces fairly well several low-lying states. First we analyze the transition amplitude, which confirms that an effective charge must be introduced to reproduce the experimental value. Then, proton and deuteron elastic and inelastic scattering are investigated by including pseudostates, which simulate the continuum. In , the deuteron breakup is taken into account with two-body pseudostates. A fair agreement with experiment is obtained without any fitting parameter. Breakup effects are in general small, but improve the agreement with experiment.
