Spherical Bessel functions

Abstract: We examine indefinite integral involving of arbitrary power $x$, multiplied by three spherical Bessel functions of the first kind $j_{h},j_{k}$, and $j_{l}$ with integer order $h,k,l \geq 0$ and an exponential. Then we add some conditions for smooth calculation in considering the general and elementary exact evaluation. Thus, by measuring their equivalents, we can verify their accuracy
