modified spherical Bessel function | spherical modified Bessel function of the first kind

A modified spherical Bessel function of the first kind, also called a "spherical modified Bessel function of the first kind", is the first solution to the modified spherical Bessel differential equation, given by i_n(x) congruent sqrt(π/(2x))I_(n + 1/2)(x), where I_n(z) is a modified Bessel function of the first kind.
