Integral of Bessel function, square root and gaussian

In summary, the integral of a Bessel function is a mathematical function used to calculate the area under the curve of a Bessel function. It can be expressed in terms of the square root function and is commonly used in physics and engineering to solve problems involving oscillations and waves. It is also used in the calculation of Gaussian distributions and has a general formula known as Watson's integral. The integral of a Bessel function has many real-world applications in fields such as engineering, physics, and statistics.

Hi! Does anyone know how to solve the following integral analitically?

[itex]\int^{1}_{0} dx \ e^{B x^{2}} J_{0}(i A \sqrt{1-x^{2}})[/itex], where A and B are real numbers.

Thanks!

Not really sure, but maybe if I take a stab at the question, someone else will answer better.

would it help to replace x=cos(θ)? then x^2 = cos^2(θ), dx =-sin(θ)dθ, [itex]\sqrt{1-x^2}=sin(\theta)[/itex] and have your integral go from θ= ∏/2 to 0.

and you might try looking carefully at each of the "recurrence relations" for Bessel functions and see if they help.
