The total neutron cross section of 11Β has been measured from 7.2 to 8.4 MeV. The analysis of all data from the 8Li(α,n0)11Β reaction in combination with the total cross section data can determine an upper limit on the stellar reaction rate of the 8Li(a,n)11Β reaction.

Stellar Reaction Rate

The reaction rate of several astrophysically important nuclear reactions is dominated by the contribution of narrow resonances at the astrophysically most effective energies. In the stellar plasma the partial width of the resonances in the entrance channel is modified due to screening corrections. This effect, so far ignored in stellar reaction network calculations, reduces the conventional Salpeterscreening enhancement of the reaction rate. We derive analytical screening correction factors for the contributions of narrow resonances to the stellar reaction rate and discuss the effects for UC (a, j)lsO, 150(a,7)19 Ne and other reactions of relevance to explosive hydrogen burning
