Excitation and Deexcitation of the Gd II Octet States

摘要

Excitation of the octet states of a singly charged gadolinium ion in e--Gd collisions is experimentallystudied by measuring 48 excitation cross sections at an electron energy of 30 eV. Four optical excitation functions are obtained within the 0-200-eV electron energy range. The validity of experimental data on the radiative transition probabilities is analyzed in terms of the feasibility of their use for determination of the branching ratios.
