摘要：

The reactions of H atoms with N atoms trapped in an N-2 matrix were studied. The N-2 matrix, containing N atoms, was formed by depositing plasma-activated N-2 gas over the surface of a cryocooler at 10-30 K. The deposited active nitrogen was reacted with H atoms by spraying plasma-activated hydrogen gas over the surface of the deposited sample. It was found that the H atoms diffuse inside the N-2 matrix and react with N atoms to form NH3 molecules. The diffusion of H atoms in N-2 and H2O matrices at 10-30 K and the absence of H abstraction from NH3 by H atoms were confirmed by an electron spin resonance experiment.
