Abstract

A review is made of the solar observations identified with the n=2-2 transitions of elements in the fourth period of the periodic table. The identifications are mainly with transitions of the solar abundant elements calcium and iron. The majority of observations are of solar flares. Some new identifications are presented with transitions belonging to the 2s**2 2p**k - 2s 2p**k+1 transition arrays and within the 2s**2 2p**k ground configurations. The transitions are useful for diagnostic purposes, such as the determination of differential emission measures and electron densities of solar flare plasmas. In such applications, it is crucial to know the extent of spectral line blending. Special attention is given to this problem.
