Role of diproton correlation in two-proton emission decay of the ${}^6$Be nucleus

Tomohiro Oishi, Kouichi Hagino, Hiroyuki Sagawa

We discuss a role of diproton correlation in two-proton emission from the ground state of a proton-rich nucleus, ${}^6$Be. Assuming the three-body structure of $\alpha +p+p$ configurati…
