Differential Cross-Section Measurements for the ~6Li(n,t)~4He Reaction at 3.67 and 4.42 MeV

摘要

A gridded ionization chember was used to meaure the diffeential cross sections for trtions from the ~6Li(n,t)~4He reaction at 3.67 and 4.42 MeV. Neutrons were produced via the D(d,n)~3He reaction. The absolute neutron flux was determined thorugh the ~238U(n,f) and H(n,p) reactions. At 3.67 MeV the result is almost 90 deg symmetric, but it is obviously forward epaked at 4.42 MeV in the center-of-amss refrence system.
