It is shown, that absorption of light by a nanoparticle can be increased by several orders because of presence of atom. It is established, that optical bistability in such system is possible.LaTeX paper, 12 pages, 6 figures, will appear in Proceedings of 4-th International Symposium `Modern Problem of Laser Physics', Novosibirsk, Russia, August 22-27, 2004Opticstext
