UNRESOLVED TRANSITION ARRAYS AND WAVE-NUMBER DISTRIBUTIONS FOR SOME E1 TRANSITIONS BETWEEN HIGH-L STATES OF THE IRON-GROUP ELEMENTS

The intensity distributions of some transitions belonging to the iron- group elements have been analyzed in the framework of unresolved trans ition array theory. More specifically, the transitions of the types l( N)(alpha(c)L(c)S(c))l'-l(N)(alpha(c)L(c)S(c))l'' and l(N)(alpha(c)L(c) S(c))s(alpha(c)L(c) Sigma(c))l''-l(N)(alpha(c)L(c)S(c))s(alpha(c)L(c) Sigma(c))l'' (l',l''greater than or equal to 4) have been considered. The possibility to characterize these transitions by the first weighte d moments of their wavenumber distributions is clearly demonstrated.
