【 摘 要 】

A new trajectory-based method of transition probability evaluation in quantum system is developed. Capabilities of the method are demonstrated on evaluating photo-excitation and photoionization probabilities in hydrogen atom under exposure of an ultra-short photopulse, and total photoionization probability in the helium atom.
