Two-protons' entanglement of the diproton emission from 17Ne halo resonant states

Fingerprints of entangled states of the two protons, from the decay of halo resonant states of 17Ne has been studied. This study makes possible a way to discern the diproton emission from the others two proton emission mechanisms. Specially we calculate the energy (E1=10.87 MeV) and the width (Γ1=3.82 MeV) of the first halo resonant state, which can also emits diproton. For this purpose, the diproton was considered as a resonant state and its width (Γs=4.049 MeV) was estimated. An analytic expression for the angular proton-proton distribution was found in agreement with experimental results. We conclude that the first 17Ne excited state can not emit diproton. We also arrive at the conclusion that there are few 17Ne excited states, having halo properties which can emit diproton. (Full Text)
