The temperature dependence of quantum diffusion of hydrogen atoms in solid H2 in the range 1.35 К<Г<4.2 К is determined experimentally. It is found that the diffusion coefficient depends linearly on temperature, indicating the existence of a new type of quantum diffusion if there is a large displacement of levels.
