PARAMETRIC INVESTIGATION OF THE ISOTOPE SHIFT IN ODD CONFIGURATIONS OF NE-I

Isotope shift measurements were performed on 33 transitions of Ne I by means of optogalvanic and intermodulated optogalvanic spectroscopy as well as saturation absorption spectroscopy. Using a large number of l ine isotope shift values obtained from both literature and our measure ments, the level isotope shifts were calculated with improved conciste ncy, Fine structure calculations were performed in odd configurations in order to obtain isotope shift parameters by means of the parametric method, 2p(5)3s: g(1) = -1077.5(7), z(2p) = 15.3(3), 2p(5)5s: g(1) = -104(26), z(2p) = 14(6), 2p(5)4d: g(1) = -42(6), z(2p) = 17(3).
