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 the "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 angstrom amplitude; the mean frequency of jumps of almost-equal-to 20 - 30 angstrom 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 load on the free end of cantilever results in damping the vibrations for 5 - 10 days. It has been deduced that the obtained results confirm the macroscopic center-of-mass quantum fluctuations and spontaneous localization of the object, predicted by the theory.
