Auger electrons measured in coincidence with the photoelectron

The dynamical parameters 11(1, k2, k3) are fixed by the photoionization matrix elements, e.g., in the LSJ-coupling approximation by the radial dipole integrals es,2P and Pcd 2p and the relative phase A, as follows  

With the help of these relations, the alignment tensor s/2q(J = 3/2 iia) was calculated and discussed in detail in Section 4.6.1.3, using numerical values for the radial dipole integrals Res2p and Red 2p and the relative phase A. 

Alternatively, these B-coefficients are also connected to the /I-coefficients used in the general parametrization formula, equ. (4.86a). In the present case one has 

The correct normalization from the photoionization process gives a factor (47i)2a ph/3 and that from the Auger decay a factor coJAn, which finally leads to 

The dynamical parameters Akik2k, together with the corresponding angular factors, then define the angular distribution pattern represented in equ. (4.86b).
