In "extended phase space" approach to quantum geometrodynamics numericalsolutions to Schrodinger equation corresponding to various choice of gaugeconditions are obtained for the simplest isotropic model. The "extended phasespace" approach belongs to those appeared in the last decade in which, as aresult of fixing a reference frame, the Wheeler - DeWitt static picture of theworld is replaced by evolutionary quantum geometrodynamics. Some aspects ofthis approach were discussed at two previous PIRT meetings. We are interestedin the part of the wave function depending on physical degrees of freedom.Three gauge conditions having a clear physical meaning are considered. They arethe conformal time gauge, the gauge producing the appearance of Lambda-term inthe Einstein equations, and the one covering the two previous cases asasymptotic limits. The interpretation and discussion of the obtained solutionsis given.
