Abstract

${}^{8}C$ is found to decay to four protons and an $α$ particle in two $2 p$ emission steps. The correlations between the protons in the first step ( ${}^{8}C$ to ${}^{6}{Be}$ ) exhibit a significant enhancement in the region of the decay phase space where the two protons have small relative energy, a region sometimes called the diproton region. The decay of the isobaric analog of ${}^{8}C$ in ${}^{8}B$ is also found to decay by $2 p$ emission. This is the first case of isospin-allowed $2 p$ decay between isobaric analog states.
