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