Fractionated single-particle states of 31Si at E/sub x/ = 5.3-9.4 MeV

A total of 40 states of ³¹Si in the region of excitation from about 5 to 9 MeV have been studied using the reaction ³⁰Si(d,p) at 10 MeV incident deuteron energy, and a biased quadrupole spectrometer. Fractionated single-particle states are identified via their forward-angle cross sections, using distorted-wave Born-approximation predictions with bound and resonance state form factors for the residual ³¹Si system. Results are contrasted with what is known of the lower lying states, from large-basis shell-model calculations and earlier (d,p) experiments.NUCLEAR REACTIONS ³⁰Si(d,p), $E_d=10$ MeV, measured σ(θ). ³¹Si deduced levels, l, j, π, spectroscopic factors.
