Abstract

A parametrization of the partial cross section of the 9Be(α, nγ)12C reaction in the α particle energy range of 0.3–7.9 MeV is presented, along with the count rates of γ quanta. The need to consider sub barrier (Eα < 1.9 MeV) α particles in plasma for temperatures Tα < 0.2 MeV is substantiated. The shapes of the Doppler broadened 4.44 MeV γ line and the count rates of γ quanta in the plasma of the JET tokamak are measured for the first time and compared to the calculated values. An estimated Tα Շ160 keV is obtained.
