The waveguide has two narrows of diameter $\\varepsilon$. The narrows play the role of effective potential barriers for the longitudinal electron motion. The part of waveguide between the narrows becomes a \"resonator\"\\, and there can arise conditions for electron resonant tunneling. A magnetic field in the resonator can change the basic characteristics of this phenomenon. In the presence of a magnetic field, the tunneling phenomenon is feasible for producing spin-polarized electron","authors_text":"B.A. Plamenevskii, L.M. Baskin, O.V.
