Abstract: For bismuth thin films on mica, the dependences of the resistivity, magnetoresistance, and Hall coefficient on the samples thickness are investigated at a temperature of 77 K. Quantum-size oscillations in the electrical and galvanomagnetic properties for films with a thickness of $<$ 50 nm are discovered. The charge-carrier free-path length is estimated. The reasons for a deviation in the observed experimental dependences from the simple theory of the quantum-size effect in semimetal films are discussed.
