Abstract
We consider Magnus force vortex dynamics in superclean superconductors and calculate the quantum tunneling rate of the pancake vortex creep from the pinning cites in the nondissipative limit. The consideration is based on the exact representation of the one-particle wave functions in the magnetic and electric fields. The obtained results are compared to the experimental data and the possibility of the observation of the discrete structure of the pinned pancake energy levels is discussed.
