摘要：

The Li-6(1+0) --> He-4 + d virtual decay vertex constant G0 and the respective asymptotic coefficient C0 of the Li-6 wave function in the He-4 + d channel are found using the analytic continuation of the solution of a novel energy-dependent phase-shift analysis of elastic d-He-4 scattering to the pole corresponding to the Li-6 ground state. The reliability and accuracy of the method used have been corroborated independently by three other ways: by direct solving the inverse problem for d-He-4 scattering and by two different methods for finding a solution for the three-body (alpha + n + p) problem. The values G0(2) = 0.42 +/- 0.02 fm and C0 = 2.93 +/- 0.15 have been found, which seem to be the most accurate and reliable among the values obtained so far.
