    "abstract": "An R-matrix analysis of experimental nuclear data on the reactions\n4He(alpha,alpha), 4He(alpha,p), 4He(alpha,d), 7Li(p,alpha), 7Li(p,p), 7Li(p,n),\n7Be(n,p), 6Li(d,alpha), 6Li(d,p), 6Li(d,n) and 6Li(d,d), leading to the 8Be\nintermediate state, has been completed in the last two years. About 4700 data\npoints from 69 experimental references are included. The excitation energy\nabove the 8Be ground state is 25-26 MeV for all reactions except\n4He(alpha,alpha) and 7Be(n,p). The data for the reactions 4He(alpha,alpha) and\n6Li(d,d) do not fit well, but the other reactions fit with a chi^2/(point) of\nless than the overall value of 7.9. Most of the 19 resonances found in the\nR-matrix analysis correspond to resonances formerly known from experiment.\nEvaluated integrated 4He(alpha,p), 4He(alpha,d), 7Li(p,alpha), 7Li(p,n),\n7Be(n,p), 6Li(d,alpha), 6Li(d,p) and 6Li(d,n) reaction cross-sections are\npresented. Evaluated cross-section and angular dependence files in ENDF format\nwere prepared for the twelve reactions p 7Li, n 7Be, d 6Li -\u003e alpha 4He, p 7Li,\nn 7Be, d 6Li. Maxwellian averaged temperature-dependent cross-sections in NDI\nformat were prepared for the six reactions 7Li(p,alpha), 7Li(p,n), 7Be(n,p),\n6Li(d,alpha), 6Li(d,p) and 6Li(d,n).",
