AbstractThe purpose of this study was the evaluation of various neutron activation cross sections using 2.8 MeV neutrons. This area of study was chosen because only a small amount of research has been done using generator produced 2.8 MeV neutrons.Most of the cross section values listed in the literature were small, requiring the use of various methods to increase the number of reactions occurring.A relative measure of the neutron flux was made using indium standards. The efficiency of the detection system was experimentally measured by the use of standardized radioisotopes.The product isotopes, produced by (n,ﻻ) or (u,n’ﻻ) reactions, and their measured activation cross sections were: 116mIn - 104 + 5 mb; 137mBa - 459 + 45 mb; 139Ba - 5.48 + 0.47 mb; 128I, - 38.5 + 3.0 mb; 56Mn - 4.28 + 0.34 mb; and 87mSr - 219 ± 26 mb. Errors from 4.8% for 116mIn to 12% for 87mSr were determined.Ball State UniversityMuncie, IN 47306
