CAN THE OBSERVED VIBRATION OF A CANTILEVER OF SUPERSMALL MASS BE EXPLAINED BY QUANTUM-THEORY

An attempt has been made to test experimentally the consequences of th e ''alternative quantum theory'' by electron microscopy technique. It has been found that the free end of a cantilever of 10(-15) - 10(-16) g in mass performs chaotic jumps of less than or similar to 100 angstr om amplitude; the mean frequency of jumps of almost-equal-to 20 - 30 a ngstrom amplitude is almost-equal-to 1 Hz. An increase in the mass of the object under observation up to (5 - 7).10(-15) g by growing the lo ad on the free end of cantilever results in damping the vibrations for 5 - 10 days. It has been deduced that the obtained results confirm th e macroscopic center-of-mass quantum fluctuations and spontaneous loca lization of the object, predicted by the theory.
