Title: Two-proton decay of the first excited state of {sup 17}Ne

Abstract

The first excited state of {sup 17}Ne has been populated via intermediate energy Coulomb excitation with a radioactive beam of {sup 17}Ne on a {sup 197}Au target to search for two-proton decay, which is in competition with the {gamma}-decay back to the ground state of {sup 17}Ne. The reconstructed invariant mass spectrum of the outgoing {sup 15}O in coincidence with two protons shows evidence for a two-proton transition from the first excited state in {sup 17}Ne as well as for transitions from higher excited states in {sup 17}Ne, which will decay via the emission of two sequential protons.
