Hey guys, I am actually solving a physics problem, and at the last step of my solution, I encounter this integral:
[tex]\int_0^{k_F} k^2J_0(k|\vec{r}'-\vec{r}|)dk[/tex]
The J is the 0th Bessel function of the 1st kind. I tried this on Wolfram alpha, and it gave me the integral in terms of other Bessel functions and Struve functions. I don't think my professor would have given me an integral that had such an elaborate solution (especially since I'm asked to graph this). Am I missing something basic here? Is there an easy way to evaluate this integral? If not, I probably did something wrong somewhere earlier.
