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 the 2p-decay of this state, which is in competition with the {gamma}-decay back to the ground state in {sup 17}Ne. The reconstructed invariant mass spectrum of the outgoing decay products {sup 15}O in coincidence with 2 protons shows evidence for a 2p-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 sequential 2p-emission.
