ANISOTROPY FACTORS FOR THE DETERMINATION OF TOTAL NEUTRON YIELD FROM THE D (d, n)He3 AND T(d, n)He4REACTIONS

摘要

Tables have been computed of the anisotropy factor, R, which is useful in determining, by the associated particle method, the total neutron yield produced in the reactions T(d, n)He and D(d, n)He3 . The range of incident deuteron energy covered is 25 to 500 keV, at associated particle colatitude angles of 90 to 180 deg. Thick-and thin-target cases have been treated. For the T(d, n)He4 reaction, the total neutrons produced per alpha particle incident on the detector is given by the relation, N = (4tt/A£2)R. In the case of the D(d, n)He3 reaction, it is more convenient to detect the pro¬tons produced in the competing reaction D(d, p)T.
