A qualitative estimation is presented for the yields of neutron and
7Be frrara
3He
3He fusion plasma by the following reactions:
3He (
3He, n)
5Be, (γ, n) reaction of the structure material (SUS316) by 10MeV γ-ray of
3He (
3He, γ) He (p, n) 3p by reaction product of protons, and,
3He (α, n)
6Be and
3He (α γ)
7Be by the same product of α Since both reactions of
3He (
3He, n)
5Be and
3He (p, n)
3p have threshold energy of-20 MeV and 10.27 MeV, respectively, neutron yield rapidly increases as ion temperature in plasma increases: i. e. the values of the fraction of the total energy released in the reaction that is carried by neutrons, “Neutronicism” are 3×10
-5 and 0.005 at ion temperature of 300 find 800 keV in the plasma with the same electron temperature, respectively. The yields by the (γ, n) reaction and
3He (αn)
6Be are less than the others. The yield of 7Be is 9×10
-5 one
3He
3He fusion reaction and
4He impurity concentration in the plasma.
