Abstract

In this work, the decay of two proton-rich isotopes of oxygen, 11, 12O was studied. The structure of these nuclei was investigated by measurement of the decay energy, intrinsic width, and momentum correlations between decay fragments. The ground and low-lying excited states of 12O were measured, including a newly observed 2+ excited state. This work marks the first observation of 11O. I also present the observation of analog states in 12O in 12N. These states decay by emission of one or two protons, and they were populated by knockout reactions of a 13O beam produced by the coupled cyclotrons at the National Superconducting Cyclotron Laboratory. The decay fragments were detected in the High Resolution Array (HiRA), an array of 14 Si-CsI(Tl) telescopes. I also present work on the experimental verification of a sinogram-based iterative reconstruction of proton stopping ratios from CT data.
