The photodetachment of the ∞H−, T−, D−, 1H−, Mu− and Ps− ions by low-energy photons is considered in terms of the two-body cluster approximation. For all considered systems the constant C in the asymptotic form of the actual three-body wavefunction is determined from highly accurate, completely non-adiabatic wavefunctions. This constant plays a central role in this method, since it allows one to determine the photodetachment cross-sections for each of the considered ions. The computed… Expand
