  An R-matrix analysis of experimental nuclear data on the reactions
4He(alpha,alpha), 4He(alpha,p), 4He(alpha,d), 7Li(p,alpha), 7Li(p,p), 7Li(p,n),
7Be(n,p), 6Li(d,alpha), 6Li(d,p), 6Li(d,n) and 6Li(d,d), leading to the 8Be
intermediate state, has been completed in the last two years. About 4700 data
points from 69 experimental references are included. The excitation energy
above the 8Be ground state is 25-26 MeV for all reactions except
4He(alpha,alpha) and 7Be(n,p). The data for the reactions 4He(alpha,alpha) and
6Li(d,d) do not fit well, but the other reactions fit with a chi^2/(point) of
less than the overall value of 7.9. Most of the 19 resonances found in the
R-matrix analysis correspond to resonances formerly known from experiment.
Evaluated integrated 4He(alpha,p), 4He(alpha,d), 7Li(p,alpha), 7Li(p,n),
7Be(n,p), 6Li(d,alpha), 6Li(d,p) and 6Li(d,n) reaction cross-sections are
presented. Evaluated cross-section and angular dependence files in ENDF format
were prepared for the twelve reactions p 7Li, n 7Be, d 6Li -> alpha 4He, p 7Li,
n 7Be, d 6Li. Maxwellian averaged temperature-dependent cross-sections in NDI
format were prepared for the six reactions 7Li(p,alpha), 7Li(p,n), 7Be(n,p),
6Li(d,alpha), 6Li(d,p) and 6Li(d,n).
