Abstract

The radiative magnetic dipole transition rate between

2 p_{\frac{3}{2}}

and

2 p_{\frac{1}{2}}

single-particle electron states has been calculated with relativistic screened hydrogenic wave functions for seven elements with

70 <~ Z <~ 93

and is found to contribute only ∼

10^{- 5}

of the total

L_{2}

level width. The result has been corroborated by an experimental study of the

Pb M

x-ray spectrum in coincidence with

K α_{1}

and

K α_{2}

x rays, establishing a limit

ω_{23} ≲ (1.4 \pm 3.0) \times 10^{- 3}

for the radiative part of the

L_{2} - L_{3} X

Coster-Kronig transition probability in Pb.
