Abstract

We study the structure of He isotopes systematically using a model in which the frameworks of the antisymmetrized molecular dynamics (AMD) and the generator coordinate method (GCM) are combined. The present AMD+GCM can reproduce basic features of the isotopes, for example halo structures in 6He and tendency of the binding energies of the isotopes within relatively small number of basis functions. In 7He, the importance of two configurations, 6Hen and (4Hen)2n, is shown for the ground state. In 8He, the calculated rms radius is smaller than the experimental one.
