One scheme of Transition Probability Evaluation
In present work are considered the scheme of
evaluation the transition probability in quantum system. It is based on
path integral representation of transition probability amplitude and its
evaluation by means of a saddle point method, applied to the part of
integration variables. The whole integration process is reduced to
initial value problem solutions of Hamilton equations with a random
initial phase point. The scheme is related to the semiclassical initial
value representation approaches using great number of trajectories. In
contrast to them from total set of generated phase paths only one path
for each initial coordinate value is selected in Monte Karlo process.

Electron-Impact Excitation of Kr 5s, 5p Levels
The available data on the cross sections of electronimpact
excitation of krypton 5s and 5p configuration levels out of the
ground state are represented in convenient and compact form. The
results are obtained by regression through all known published data
related to this process.
