Nuclear Radius and Many-Body Problem

Abstract

The radioactive $\alpha$-decay is discussed as a many-body problem. The nuclear radius is found to be 13 · ${10}^{-13\mathrm{}}$ cm±10 percent, as compared to 9 · ${10}^{-13\mathrm{}}$ in the older theory. The increased radius makes the theoretical cross section for the disintegration of heavy nuclei by deuterons agree with experiment.
