    Notes: Abstract Laser-atomic-beam investigations of the lithiumD 1- andD 2-line in magnetic fields were performed using cw-laser excitation and fluorescence detection. For both isotopes6Li and7Li, the hyperfine splittings of the ground level 22 S 1/2 and the upper level of theD 1-line, 22 P 1/2, as well as the isotopic shifts of theD 1- and theD 2-line were determined from the registrations without field. In magnetic fields, Zeeman- and Paschen-Back-effects of the lines were studied. Using the Zeeman pattern of theD 1-line for a calibration of the field strength, values for the hyperfine constantsA andB of the 22 P 3/2-level of7Li could be derived from the Zeeman pattern of theD 2-line.

    Notes: Abstract The TaI line 6356.14 Å, up to now classified as the transition 5d 36s 2 a 4 P 5/2−5d 36s(a 5 F)6p z 4 F 7 2/0 , is a blend with a second transition, which is related to the additional levels 5d 4(b 3 G)6s a 4 G 9/2−39641.24 cm−1 J=7/2°. Using laser excitation with optogalvanic and laser-induced fluorescence detection, the hyperfine constants of the four levels involved and the distance of the center wavelengths of the two fine structure transitions could be determined.

    Notes: Abstract The hyperfine structure of several spectral lines of the neutral tantalum atom was investigated by means of saturated optogalvanic laser spectroscopy. From the spectra, we have determined the magnetic hyperfine interaction constants A and the electric quadrupole interaction constants B of 14 levels with even parity and 23 levels of odd parity.
