Paper Abstract

Results of investigations of high excited states of a quantum anharmonic oscillator in close to dissociation boundary are represented. Using the quasienergy method we are obtained an equation for the calculation of energy spectrum in the quasiclassical region. This equation is solved numerically. The main results are as follows: (1) At N less than 107, where N is the quantum number, the dependence EN on (omega) has a character of a diffusion and asymmetric peak in close to the resonance frequency. The peak is higher, if an amplitude of a field is the higher. (2) At N greater than 107 the dependence EN((omega) ) has an oscillation character and also quasicrossings of energy levels take place.
