Highlights / Results

• The ³⁵Cl(n,p)³⁵S and ³⁵Cl(n,a)³²P reactions were measured using quasi-monoenergetic neutrons from the High Flux Neutron Generator (HFNG).
• The cross-section for ³⁵Cl(n,a) agrees somewhat well with ENDF calculations. 
• The ³⁵Cl(n,p)³⁵S cross-section is much lower than the ENDF/B-VII value.
• Structure is observed in the ³⁵Cl(n,p) reaction, consistent with a previously observed level at 11.24 MeV.
• This finding highlights the need for additional energy differential measurements to better understand reactions in this intermediate energy region.
• The results have been published in Physical Review C, and input into EXFOR is in process.
