Investigation of the 37Ar(n,p)37Cl and 37Ar(n,alpha)34S reactions as a function of the neutron energy

Authors

Description

The energy dependent 37Ar(n,p)37Cl and 37Ar(n,alpha)34S reaction cross sections were determined for the first time in an experimental effort involving three large facilities: the cyclotron of the UCL (Louvain-la-Neuve, Belgium) where implanted 37Ar samples were produced; the high flux reactor of the ILL (Grenoble, France) where thermal (n,p), (n,alpha_0) and (n,alpha_1) cross sections of (37+/-4)b, (1070+/-80)b and (290+/-50)mb respectively could be determined, and the GELINA neutron time-of-flight facility of the IRMM (Geel, Belgium) where strong resonances were observed in the keV region.
