Sn using single neutron knockout reaction*

The region surrounding ¹⁰⁰Sn is significant 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. Thus, experimental determination of spin-parity assignments for the lowest single-particle states in the proton-rich Sn isotopes is of vital importance. 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 momentum distributions for the ground and first excited states will be used to determine their spin and parity. The cross sections measured from the neutron knockout, once extracted, will be compared to calculations. This will give insight into the fragmentation of single-neutron strength occurring in the ¹⁰⁰Sn region. Preliminary results of the data analysis will be presented.
