Abstract
Preliminary results of one-neutron removal reactions on the nuclei 34,35Si and 37S at the intersection of the 1s0d and 1p0f neutron shells are reported. Momentum distributions of the projectile residues have been measured at the National Superconducting Cyclotron Laboratory at Michigan State University. The populated final states in the neutron removal reactions could be resolved by measuring the γ rays from the de-excitation of bound states using a position-sensitive NaI(T1) array. Partial cross sections to specific final states have been deduced. A comparison of the cross sections in the reactions (35Si,34Si) and (37S,36S) shows differences that point to the influence of intruder configurations in the vicinity of 34Si.
