Abstract
The theoretical approach to the two-proton radioactivity and three-body
decays developed in (L.V. Grigorenko, R.C. Johnson, I.G. Mukha,
I.J. Thompson, M.V. Zhukov,
Phys. Rev. Lett. 85, 22 (2000) and to be published in Phys. Rev. C) is applied to the range of
light nuclear systems. We study nuclear structures,
widths, and momentum correlations for the decay fragments.
Strong contradictions with experiment, as well as effects
of special interest, are found in
12O and
16Ne nuclei.
