Abstract
Two natural polyisotopic potassium beams were illuminated respectively by a RF modulated and an unmodulated laser beam. The laser side band frequency is locked on an atomic frequency, while the unmodulated laser frequency is RF scanned. The RF accuracy of the frequency scale allows measurements to about 0.3 MHz of the hyperfine structures and the isotope shifts of the D1 and D2 lines of 39,40,41K. The results obtained are reported and compared to the previous ones.Keywords
