Structural study of <sup>105</sup>Sn using single neutron knockout reaction

ORAL

Abstract

The region surrounding 100Sn is of significant importance due to its proximity to the N=Z=50 magic numbers, its relevance to the rp-process, and its position near the proton drip line. The determination of spin-parity assignments for the lowest single-particle states in the neighboring isotopes is important in understanding the intricate nuclear structure and in calculating the properties of nuclei in the neutron-deficient A~100 region. In this work, a one-neutron knockout reaction was performed on a 106Sn beam to measure the single-particle structure of 105Sn using the S800 and GRETINA at FRIB. Measurements of the momentum distributions of the ground and first excited states will be used to determine the spin-parity assignments. The cross sections measured from the neutron knockout, once extracted, will be compared to calculations. This will give information about the fragmentation of single-neutron strength occurring in the region around the N=Z=50 closed shells. Preliminary results of the data analysis will be presented.
