摘要：

Spectroscopic studies of the production of MgII ions from atomic metastable states by electron impact in crossed atomic and electron beams were made. Cross sections for excitation of the strongest spectral transitions and their energy dependences were determined. The maximum value of the cross section for ionization with excitation of the 3(2)S(1/2)-3(2)P(3/2) transition reached 2.4 x 10(-16) cm(2). Possible mechanisms of production of excited ions from metastable states and their contribution to the total ionization process are discussed. (C) 2000 MAIK "Nauka/Interperiodica."
