HYPERFINE STRUCTURES AND ISOTOPIC SHIFTS OF THE CU D(1) AND D(2) LINES MEASURED BY HIGH-RESOLUTION LASER FLUORESCENCE SPECTROSCOPY WITH A COLLIMATED ATOMIC-BEAM

The hyperfine A- and B-factors of the 4S-2(1/2), 4P-2(1/2) and 4P-2(3/2) states as well as the isotope shift of the related D1 and D2 resonance lines have been measured with high accuracy for copper. High-resolution laser fluorescence spectroscopy and a collimated atomic Cu beam have been employed to reduce Doppler and pressure broadening. The measurements are in good agreement with literature data and improve the accuracy of the 4P-2(1/2) hyperfine structure considerably, and that of the isotope line shifts by more than one order of magnitude.
