Neutron transfer near the N=20 Island of Inversion with the <sup>29</sup>Mg(d,p)<sup>30</sup>Mg reaction
ORAL
Abstract
We have studied the 29Mg(d,p)30Mg reaction using the SOLARIS spectrometer at FRIB. Understanding the structure of 30Mg informs us about the properties of neutron-rich Mg isotopes approaching the N=20 Island of Inversion. Only a few states in 30Mg have firm spin-parity assignments, and little is known about the negative-parity levels formed by fp-shell particle-hole excitations, which are strongly populated in the (d,p) reaction. We performed the measurement in inverse kinematics with a reaccelerated 29Mg beam produced by the ReA6 facility at FRIB. The 29Mg beam intensity was approximately 50000 particles per second, bombarding a 200 micro-gram/cm2 CD2 target. Protons and recoiling 30Mg nuclei were detected in the SOLARIS solenoidal spectrometer, providing high-resolution measurements for final states in 30Mg. We will present a preliminary analysis of the data, and compare the results to the predictions of shell-model calculations for 30Mg.
