Analytical evaluation of an infinite integral over four spherical Bessel functions

An infinite integral over four spherical Bessel functions of the form ∫0∞r2jλ1(k1r)jλ2(k2r)jλ3(k1r)jλ4(k2r)dr is analytically evaluated. The result involves a finite sum over an associated Legendre function of integer degree and half integer order with a real argument greater than 1.
