| Abstract: | By using laser fluorescence spectroscopy we measured the hyperfine structures of three second-step transitions(0 cm -1→1 6856 cm-1→34272 cm-1),(3010 cm-1→20082 cm-1→36853 cm-1),(3010 cm-1→20082 cm-1→37544 cm-1) in a La hollow cathode discharge lamp. The a coefficients of 34272 cm -1,36853 cm-1,and 37544 cm-1 levels have been calculated. The results given in this paper are first reported. |
