How to get the second electron affinity of tellurium?

I need the value of the second electron affinity of Te, i.e. the energy change associated with the attachment of an electron to a $\ce{Te-}$ anion
$$\ce{Te- + e- -> Te^{2-}}$$
In the books (e.g. J. Huheey, E. Keiter, R. Keiter; Inorganic Chemistry: Principles of Structure and Reactivity, 4th Ed.) I find second electron affinities only for certain elements from the periods 2,3,4 of the Periodic Table but not for tellurium.


I found a paper[1] that shows how to calculate the second electron affinities, for different elements, and gives an example how to do it for the oxygen. 


The calculations use Coulomb and exchange integrals $\mathrm{J\_{xy}}$ and $\mathrm{K\_{xy}}$ for two electrons in different 2p orbitals, and with the same spin. 


Do I understand correctly, for tellurium, I need the values of these integrals for two electrons in different 5p orbitals, and with the same spin?


Is there any software package where I can calculate these integrals or is there a paper or a book where these values are calculated? Is there another way to calculate the second electron affinity of Te or a paper where it is calculated or measured?
