Аннотация
A method for calculating the spectrum of ionized electrons is developed based on a solution of the equation of quantum system evolution in expanding space in the hydrodynamic representation. Using one-dimensional test problems, it is shown that the proposed numerical algorithm provides results with satisfactory accuracy for smooth initial distributions, but needs improvement in cases when the system wave function has zeros.
