We will report on a recent measurement using the 36S(d, 3He)35P reaction in inverse kinematics with the Helical Orbit Spectrometer (HELIOS) at ATLAS (ANL). Thanks to the unique capabilities of HELIOS, enhanced with a recoil detector setup, it is possible to perform the reaction in nearly background free conditions.
An analysis of the reconstructed 3He spectrum in HELIOS did not show a peak that could be associated with the 1/2_2 intruder state in the region of interest with an intensity greater than 5% of the ground-state. This result provides an additional constraint to state-of-the-art theoretical descriptions to further understand the evolution of shell structure in the region.
*This research was funded by LBNL-LDRD (LDRD NS16-128), and by the DOE (DE-AC02-05CH11231 and DE-AC02-06CH11357). It used ANL’s ATLAS facility, which is a DOE User Facility.
