Abstract

A new cascade-decoupling technique has been used to measure hyperfine intervals (in MHz) of the following excited

S

states of alkali-metal atoms:

K^{39} (6 {}^{2}S_{\frac{1}{2}}) 46 \pm 2

;

K^{41} (6 {}^{2}S_{\frac{1}{2}}) 26 \pm 2

;

{Rb}^{85} (7 {}^{2}S_{\frac{1}{2}}) 270 \pm 10

;

{Rb}^{85} (8 {}^{2}S_{\frac{1}{2}}) 135 \pm 15

;

{Rb}^{87} (7 {}^{2}S_{\frac{1}{2}}) 565 \pm 60

;

{Rb}^{87} (8 {}^{2}S_{\frac{1}{2}}) 290 \pm 20

;

{Cs}^{133} (8 {}^{2}S_{\frac{1}{2}}) 680 \pm 120

; and

{Cs}^{133} (9 {}^{2}S_{\frac{1}{2}}) 405 \pm 30
