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