摘要：

The adsorption of atomic hydrogen on graphene monolayer is considered using the model density of states (M model). Analytical expressions for the density of states of H adatom and its occupation number n(a) are obtained. The main (local) contribution n(l) to the total occupation number n(a) is due to a local level of the adatom, which occurs below the edge of the continuous spectrum. A variant of the surface molecule approximation in the case of n(l) >> n(a) - n(l) is proposed.
