Continuum nuclear structure of light nuclei.

摘要

In this work, the continuum decay of proton-rich nuclei with mass number A ≤ 17 was studied. The nuclear structure of these nuclei was assessed by measuring the decay energy, width, and momentum correlations between the decay fragments. In particular the Isobaric Analog State in 8B, the ground-state and excited states of 16Ne, the T = 3/2 states in the A = 7 isobaric chain, and the excited states of 9C and 17Ne were all studied. In addition a first measurement of 17Na was made. These states decay by emission of 1 or more protons and were populated through knockout reactions or inelastic scattering of 9C and 17Ne secondary beams produced at the National Superconducting Cyclotron Laboratory. The charged parti- cles were detected in the High Resolution Array (HiRA) which, in these studies, consisted of 14 Si-CsI(Tl) telescopes. Gamma rays measured in coincidence with charged particles were measured in the 4pi array of CsI(Na) called CAESAR.
