Mathematica: Evaluating integral

[Niles]

Hi

I need some assistance with the attached integral. I have tried performing it in Mathematica, but it doesn't give me the result in closed form. It just shows the integral.

I have attached my notebook if someone wants to test it out. I would be very happy to receive some feedback as I have spent many hours trying to make this work.

It has successfully done the two inner integrals and fails on the final integral.

If I have not made a mistake then a substantially simplified version of your third integral is

Integrate[(vZ*Erf[vZ]^2)/E^vZ^2, {vZ, 0, Infinity}]

and there does not appear to be a closed form solution to that so I do not expect your actual problem has one either.

Thanks, I believe you are right.Niles.
