▎ 摘  要

We demonstrate that spectrum rearrangement can be considered a precursor of and basis for the metal-insulator transition observed in graphene dosed with hydrogen atoms. The Anderson-type transition is attributed to the Fermi level's entering into the quasigap, which develops in the vicinity of the impurity resonance energy because of the anomalous spectrum rearrangement. The theoretical results for the Lifshitz impurity model are in a reasonable agreement with the available experimental data.
