Isotope shifts and hyperfine structure in the transitions of stable calcium isotopes and calcium-41

摘要: Isotope shifts and hyperfine structure in the 4s2 1S0 → 4s4p 1P1 4s4d 1D2 transitions of calcium have been measured with high-precision laser spectroscopy. Calcium atoms an atomic beam were excited single-frequency cw dye titanium sapphire lasers then photoionized 363.8 nm or 514.5 line argon ion laser. The resulting ions analyzed detected a quadrupole mass spectrometer. for all stable isotopes radionuclide 41Ca both transitions. corresponding field shift specific coefficients as well constants 41, 43Ca derived. results are compared previous work values 41,43,46Ca state reported first time.
