Abstract

In xenon, the

5 p^{5} 5 d {[K = \frac{5}{2}]}_{J = 3}

and

5 p^{5} 5 d {[K = \frac{7}{2}]}_{J = 3}

atomic states have been excited by two-photon absorption from the ground state. It is shown that the two-photon absorption proceeds via off-resonant

E 1 - E 2

and

E 2 - E 1

transitions. Satisfactory agreement is found between experimental and estimated two-photon absorption rates for these processes.
