Abstract: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.
