Experimental and theoretical data on tunneling and barrier-suppression ionization of atoms and atomic ions in a low-frequency laser radiation field are considered. The yields of single- and multi-charged ions, the energy and angular distributions of photoelectrons, and effects of the laser pulse length and laser polarization are analyzed.
