Outline of Final Research Achievements

Quantum interference and diffraction of the neutrino were solved　based on the fundamental principle of the quantum mechanics. The transition probability bridges the physical law with natural phenomena and the formula derived by Dirac in 1927, which has been considered rigorous and used in wide area of natural science,　was revised by the present project. A new formula that includes the old one and a new correction term, which is larger than the original one in certain situation, is derived. For the neutrinos, the correction terms give macroscopic quantum phenomena that depends on the absolute neutrino masses. Based on this, a new method for its determination is proposed. The correction terms were shown to give significant effects to many other phenomena, especially to those that have not been understood well with the old formula.
