Measurement of the hyperfine structure of the8P122state ofRb87and the9P122state ofCs133

Abstract
The hyperfine structure of the 8P122 state of Rb87 and the 9P122 state of Cs133 has been measured by a multistep excitation method using a dye laser. Our measured values for the magnetic dipole coupling constant are A(Rb87, 8P122)=32.12(11) MHz and A(Cs133, 9P122)=23.19(15) MHz.
