Abstract

Unresolved Transition Arrays (UTA) appear in the X-UV spectra of highly ionized heavy atoms when the numerous lines of an array merge together due to line broadening. UTA are described as distributions of transition energies characterized by their mean and variance. Explicit formulas for these are described and discussed. Agreement with experiment is very good. This opens the way to identification of spectra without resorting to single lines. Possible applications are pointed out.
