dc.description.abstract Rare isotopes are nuclei with very short half-lives and can have a large asymmetry of neutrons to protons. These isotopes can have unusual structures such as halos that can exhibit a phenomenon known as a Soft Dipole Resonance (SDR). One rare isotope of interest is 8-Helium (<sup>8</sup>He) which is the most neutron-rich bound nucleus currently known, with a neutron to proton ratio of 3. In previous investigations of <sup>8</sup>He two excited states (2<sup>+</sup> and 1<sup>+</sup>) were observed with drastically conflicting reportson their locations. The inconsistent reports on the 2<sup>+</sup> state, in particular, have been postulated to be due to the excited state being mixed with a low-lying SDR state. Through an experiment conducted at the IRIS facility located at TRIUMF, Canada&rsquo;s particle acceleration center, the excited spectrum of <sup>8</sup>He has been investigated. The goal of this study is to get additional measurements on the excited states of <sup>8</sup>He as well as explore the possibility of the 2<sup>+</sup> state being mixed with a SDR. In this thesis,I will outline the experimental set up and the data analysis to determine the Q-value spectrum of <sup>8</sup>He from the <sup>8</sup>He(d,d&prime;) <sup>8</sup>He<sup>&lowast;</sup> reaction. en_CA
