Abstract
The two-potential formula is used to find the change in the s-wave sca ttering length of a pair of colliding particles induced by a change in their interaction potential. It is illustrated by a calculation of th e scattering length of hydrogen atoms interacting through the X (1) Si gma(g)(+) molecular state. The b (3) Sigma(u)(+) scattering length is also calculated with a recent potential.
