Excitation of doublet states of yttrium atom by electron impact
Annotation
The excitation of odd doublet states of yttrium atom by slow monoenergetic electrons is investigated. The obtained experimental values of the excitation cross sections of spectral lines of YI are used for the calculation of the excitation cross sections of energy levels. The levels pertaining to the termsx x2P, y2D, and y2F have the largest total excitation cross sections. The contribution by cascade population is about 20% for the levelsz z2D and about 3.5% for the levelsz z2F.
