  In this paper, the integral $\pmatrix{\lambda_1 &\lambda_2 &\lambda_3\cr 0 &0
&0\cr}\, \int_0^\infty \, r^{\lambda_3+2}\, \exp{(-\alpha r^2)}\,
j_{\lambda_1}(k_1r) \,j_{\lambda_2}(k_2r) \,dr$, where $k_1$, $k_2$ and
$\alpha$ are positive, is evaluated analytically. The result is a finite sum
over the modified spherical Bessel function of the first kind. This result will
be useful for nuclear scattering calculations, where harmonic oscillator
nuclear wavefunctions are used or when evaluating momentum space matrix
elements for a Gaussian potential.
