Abstract :
Summary form only given. A method for the measurement of the acceleration of gravity, which is based on the fact that for fixed vertical position, the frequency of small mechanical oscillations of a superconducting levitated body placed in the nonuniform magnetic field of a coil energized by a direct current is independent of the levitated mass, is proposed. Peculiarities and errors of the method are discussed.<>
