Abstract

We present the results of our recent experiments for physicochemical processes of hydrogen such as tunneling reaction and surface diffusion on amorphous solid water at low temperatures as low as 10 K, which are closely related to chemical evolution on cosmic ice dust in a very cold region of space, so-called molecular cloud.
