Abstract
We study the emission of two protons from nuclei where this is the only decay channel. A three-body model is developed. We compare the “diproton” model with the three-body calculations. We present exploratory studies of the and ground states, which are good candidates for two-proton radioactivity. The two-proton width for the state is also estimated. Our calculations give substantially lower values for the width than predicted by the diproton model, but larger than from direct decay to the continuum.
