QUASI-DISCRETE FEATURES OF THE CONTINUOUS ENERGY-SPECTRUM - AN APPLICATION TO METASTABLE XE-XE PAIRS

A quantum-mechanical treatment of the stationary wavefunctions of vibr ationally and rotationally highly excited quasi-bound xenon excimers i n the electronic state O-u(+) is presented. A simple analytical method is proposed that can be realized with the help of special software su ited for fast high-precision calculations. For this purpose, the compu ter programming language UBASIC is used. Quasi-discrete features of th e continuous energy spectrum are discussed and demonstrated. The spect rum of quasi-bound excimers consists of narrow resonance-like peculiar ities that can be treated as quasi-discrete vibrational levels. The en ergy dependence of the phase shift is established for quasi-bound xeno n excimers.
