Abstract

The Ar-37(n(th),alpha)S-34 and Ar-37(n(th),p)Cl-37 reactions were studied at the high flux reactor of the ILL in Grenoble, For the Ar-37(n(th),alpha(0))S-34 and Ar-37(n(th),p)Cl-37 reaction cross sections, values of (1070 +/- 80) b and (37 +/- 4) b, respectively, were obtained. Both values are about a factor 2 smaller than the results of older measurements. The observed suppression of the Ar-37(n(th),alpha(1))S-34 transition could be verified from theoretical considerations. Finally, evidence was found for the two-step Ar-37(n(th),gamma alpha)S-34 process. (C) 1999 Elsevier Science B.V.
