Momentum correlations in two-proton and other multi-body decays of light proton-rich nuclei are discussed. The variety of such decays are illustrated by a number of examples. The measured correlations for the ground state of {sup 6}Be are found to be consistent with the cluster-model calculations of Grigorenko et al. The ground state of {sup 8}C decays by two sequential steps of 3-body (two-proton) decay passing through the {sup 6}Be{sub g.s.} intermediate state. The isobaric analog of {sup 8}C in {sup 8}B undergoes two-proton decay to the isobaric analog state in {sup 6}Li. To the extent that isospin is conserved, this is a Goldansky-type decay, i.e. the isospin-allowed immediate state in {sup 7}Be is energetically forbidden. An excited state in {sup 10}C is found to have a {approx}50% four-body-decay branch where the protons have a strong diproton character.
