Two-proton radioactivity — a curiosity of nature? Original Research Article

In the present paper, we describe recent results on two-proton mission studies. In the first part, new results on two proton emission from excited states in17Ne are presented. In these complete kinematics measurements performed at the SPEG facility of GANIL, the angle between the two proton has been measured evidencing a2He emission pattern. In a second part, recent results on the two-proton radioactivity of45Fe from GANIL and GSI are presented, which show the first evidence of this new radioactivity.
