{sup 8}C is found to decay to four protons and an {alpha} particle in two 2p emission steps. The correlations between the protons in the first step ({sup 8}C to {sup 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 {sup 8}C in {sup 8}B is also found to decay by 2p emission. This is the first case of isospin-allowed 2p decay between isobaric analog states.
