摘要：

We have investigated the 4s S-2(1/2) -> 5p P-2(1/2) transition (D-1 line) of the potassium isotopes K-39, K-40, and K-41 using Doppler-free laser saturation spectroscopy. Our measurements reveal the hyperfine splitting of the 5p P-2(1/2) state of K-40, and we have determined the specific mass shift and the nuclear field shift constants for the blue (405 nm) D-1 line.
