  One can construct the model conception of quantum phenomena (MCQP) which
relates to the axiomatic conception of quantum phenomena (ACQP), (i.e. to the
conventional quantum mechanics) in the same way, as the statistical physics
relates to thermodynamics. Such a possibility is based on a new conception of
geometry, which admits one to construct such a deterministic space-time
geometry, where motion of free particles is primordially stochastic. The
space-time geometry can be chosen in such a way that statistical description of
random particle motion coincides with the quantum description. Methods of MCQP
in investigation of quantum phenomena appear to be more subtle and effective
than, that of ACQP. For instance, investigation of the free Dirac equation in
framework of MCQP shows that the Dirac particle is in reality a rotator, i.e.
two particles rotating around their common center of inertia. In the framework
of MCQP one can discover the force field, responsible for pair production, that
is impossible in the framework of ACQP.
