title: Threshold behavior and analytical fitting of partial wave capture probabilities for attractive R(-n) potentials.
abstract: Numerically accurate analytical fittings for partial wave capture probabilities in the field of R(-n) potentials (n = 4 and 6) are presented across practically interesting ranges of probabilities. The results demonstrate the performance of the Bethe and Wigner threshold laws at low collision energies and should be useful for practical applications.
