摘要: Matrix elements between vibrational continuum states are difficult to manipulate because the matrix continuously indexed and typically divergent. Use of Airy wavefunction basis is shown yield tractable xn consisting Dirac delta function its derivatives. Such an may be suitable for use in collision-induced dissociation studies. The used solve time-dependent Schrodinger equation forced harmonic oscillator; agreement with analytical transition probabilities good. This simple system reveals aspects which influence numerical accuracy. Means transforming from oscillator or piecewise-analytic representations also discussed.
