Elementary processes of nuclear fusion reaction in solids have been studied by providing the sample in a vacuum system. The key factor of this study is heterostructures fabricated by depositing thin film oxides and Au on one and the other surface of deuteron-loaded palladium (Pd-D) plate. Using this method, we have detected ^4He production by the real time observation using high-resolution quadrupole mass (Q-mass) spectroscopy. It has been shown that the peak attributable to ^4He mass (4.0026 amu) appeared chaotically when the sample's temperature increased rapidly. The system of H-loaded (Pd-H) heterostructure, on the other hand, produced no peak at 4.0026 amu. We have also confirmed that the peak at 4.0026 amu in the Q-mass spectra is not due to the existence of contaminated ^4He in the air or in the D_2 cylinder used. This result indicates that a new class of nuclear fusion occurs in condensed matter.
