“…The excitation energy and intrinsic width of these proton decaying states can be accessed via the invariant mass of the detected decay fragments. With the apparatus used for the present work, this continuum-spectroscopy technique has been used to study the ground and excited states of 16 Ne [1,2] and the isobaric analog state in 8 B [3]. For two-proton decaying states, this method can also determine whether the decay occurs directly or by two sequential one-proton decays through an intermediate nucleus by measuring the energy and angular correlations between the decay fragments.…”

“…Invariant-mass spectroscopy with fast radioactive beams has proven a valuable tool for studying the structure of light exotic isotopes near the drip lines. With the High Resolution Array (HiRA) [1], we have focused our studies on states produced in nucleon knockout reactions for isotopes near and beyond the proton drip line [2][3][4][5][6]. However in the same experiments, we also obtained data for a number of other reactions types [3,7].…”

Neutron transfer reactions with fast secondary beams of 17 Ne, 15 O, and 9 C have been studied with the HiRA and CAESAR arrays. Excited states of 18 Ne, 16 O, and 10 C in the continuum have been identified using invariant-mass spectroscopy. The best experimental resolution of these states is achieved by selecting events where the decay fragments are emitted transverse to the beam direction. We have confirmed a number of spin assignments made in previous works for the negative-parity states of 18 Ne. In addition we have found new higher-lying excited states in 16 O and 18 Ne, some of which fission into two ground-state 8 Be fragments. Finally for 10 C, a new excited state was observed. These transfer reactions were found to leave the remnant of the 9 Be target nuclei at very high excitation energies and maybe associated with the pickup of a deeply-bound 9 Be neutron.
