A108500300011 On this basis, the total cross section for production A108500300012 of high energy He3(d,gamma) capture radiation at the A108500300013 peak of the excitation curve is calculated to A108500300014 be (0.057+-0.010) mb. A108500300015 (2) As a check on the first method, a calculation was A108500300016 also made of the absolute sensitivity of the NaI A108500300017 crystal for 16.6-MeV gamma-rays. This calculation was A108500300018 based on the gamma-ray cross sections contained in A108500300019 ref. (see REL-REF, C.M.Davisson+).
