Symbolic Integration, how to count when int can not compute?

I have an unusual function with several symbolic parameters,that contains integral. I am trying to fit this function later to experimental data and acquire those parameteres. I tried to use 'integral', but it requires a function without any symbolic variables. Then I tried 'int', but the integral is too complicated and even after 30 mins I get no result- 'busy'. Is there any other method for integral solving?
Function looks like this-
photo and below it there are 4 parameters that we look for, all besides Ri which is our 'x' We know re, ri and Ri as Data of course. R=sqrt(Ri^2+ri^2+r^2)
For the clarity of this post I put the code in my second post.

It would be easier to answer this question if you showed us the function.

Use the curve fitting app ( cftool ) or lsqcurvefit to fit to the data finding those coefficients.
The use of a symbolic integral here does not sound necessary.
