Neutron transfer near the N=20 Island of Inversion with the 29Mg(d,p)30Mg 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.
