MAGNETIC SUBLEVEL PARTIAL-DIFFERENTIAL CROSS-SECTIONS FOR ELECTRON-IMPACT EXCITATION OF THE BA(...6S6P 6(1)P1) LEVEL

Magnetic sublevel partial differential cross sections for excitation o f the Ba(...6s6p 6(1)P1) level are presented based upon the differenti al cross section measurements of Jensen et al and Wang et al in combin ation with new electron impact coherence parameter measurements and el ectron impact coherence parameter measurements previously reported by Zetner and Li. These partial differential cross sections, determined f or electron impact energies of E0 = 10, 20, 37, 50 and 80 eV, are comp ared with available theory.
