摘要：

The possibility is considered of two-photon ionization of atomic particles, with the atomic (ion) level quantum being in quasi-resonance with an intense incoherent monochromatic VUV light under natural conditions, for example, inside planetary nebulae in the vicinity of bright stars. The collisionless resonance-enhanced photoionization mechanism considered may give rise to multiply charged ions as a result of successive (multiple) resonance-enhanced ionization of the photoions produced in a rarefied media with a very low rate of recombination.
