Differential and Angle-Integrated Cross-Section Measurement for the ⁶Li(n,t)⁴He Reaction at E_n = 1.05, 1.54, and 2.25 MeV

Abstract

Differential cross sections and angle-integrated cross sections of the ⁶Li(n,t)⁴He reaction were measured at E_n = 1.05, 1.54, and 2.25 MeV by using the gridded ionization chamber method. A ⁶LiF sample and a ²³⁸U sample were set back-to-back inside the twin chamber for measurement. Neutrons were produced through the T(p,n)³He reaction. The absolute neutron flux for E_n = 2.25 MeV was determined by the ²³⁸U(n,f) reaction, and those for E_n = 1.54 MeV and E_n = 1.05 MeV were determined by a calibrated BF₃ long counter. Present results are compared with existing data.
