摘　　要：There is considerable interest in potential aneutronic fusion reactors. One possible reaction is^(11)B(p,a)2a.However, the emitted alpha particles are energetic enough to generate neutrons by interacting with boron inside the reactor through the ^(11)B(α,n)^(14N) and ^(10)B(α,n)^(13)N reactions.To aid in evaluating neutron production within this potential aneutronic reactor, the total cross sections were measured for the ^(11)B(α,n)^(14N) reaction between 2 and 6 MeV and for the ^(10)B(α,n)^(13)N reaction between 2 and 4.8 MeV. The results are presented and compared with previously reported results.There is considerable interest in potential aneu- tronic fusion reactors. One possible reaction is 11B（p,α）2α.
