Does anyone have a clue about how to solve this integral? Will it have a closed form?
$\int_0^\infty e^{-x^2}J_n(ax)J_n(bx)dx$
I've been searching materials and papers for a while, and did find anything about it... People had this integral $\int_0^\infty x^2e^{-x^2}J_n(ax)J_n(bx)dx$ solved instead of the above form.
