Evidence of non-statistical properties in the $^{35}$Cl(n,p)$^{35}$S cross section

ORAL

Abstract

The $^{35}$Cl(n,p)$^{35}$S and $^{35}$Cl(n,$\alpha$)$^{32}$P cross sections at incident neutron energies between 2.42 - 2.74 MeV, were measured using the Berkeley High Flux Neutron Generator (HFNG). $^{35}$Cl(n,$\alpha$) cross sections were consistant with the neutron capture data libraries. The cross sections for $^{35}$Cl(n,p) however, were more than a factor of three to five less than all of the values in the data libraries. The measured energy-differential cross section in this reaction is consistent with a single resonance with a width of 257(27)~keV. This result suggests that, despite the high incident neutron energy, any attempt to model (n,x) cross sections in the vicinity of the N = Z = 20 shell gap requires a resolved resonance approach rather than a Hauser-Fesbach. Future studies by our group will be presented and discussed.
