The resulting potentials are in excellent agreement with the potentials independently obtained from molecular beam scattering measurements. The potentials have been used to predict...

The thermal lens, formed by the degradation of the absorbed light energy as heat by the sample, allows the employment of a nonequilibrium method in the critical region. Controlling the refractive-index gradient, i.e., a density gradient, perturbations can be maintained at levels...
