Zeeman effect of atomic uranium in the high lying odd levels measured by laser induced fluorescence spectroscopy

We measured Zeeman effect of atomic uranium spectra using laser induced fluorescence spectroscopy, and derived the J-value and g-factor of the second step levels. J-values and g-factors of high lying odd levels could be obtained. These data, especially the g-factors, have almost been unknown so far. We could verify our method which can be useful to measure J-values and g-factors of high lying levels of complex atoms like uranium

Isotope shift and hyperfine structure of the highly excited atomic uranium

The laser induced fluorescence method using atomic beam combined with Doppler-free two-photon absorption technique was applied for the measurement of isotope shifts and hyperfine structures of atomic uranium including 234U, 235U, 236U and 238U isotopes. The isotope shifts between 238U–234U, 238U–235U, 238U–236U, and the hyperfine structure of 235U were obtained in the high lying odd levels around 4 eV
