Quantization Of Nuclear Mass Defect And Mass Differences In Atoms Of The Same Isotope

According to the fact of nuclear mass defect, and combined with the quantization features generally existing in microcosm, a quantization hypothesis of nuclear mass defect is proposed, which assumes that different atoms of the same isotope of an element could have different masses. The rationality of this hypothesis is verified by the change in nuclear state, the accuracy of the measurement of isotopic atomic mass, and the Einstein's Equation of Mass and Energy, and several experimental ideas are given. The high-precision atomic weight data is used to search for the quantum of the mass defect and obtain an alternative mass quantum. Also, this paper proposed a small neutron hypothesis about the mass defect, which assumes that the nuclear mass defect is the mass reduction of an object with actual mass; the nuclear mass defect is the result of small neutrons loss.
