摘要
C-8 is found to decay to four protons and an a particle in two 2p emission steps. The correlations between the protons in the first step (C-8 to Be-6) 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 C-8 in B-8 is also found to decay by 2p emission. This is the first case of isospin-allowed 2p decay between isobaric analog states.
