r"""Returns an array of multi-group cross sections.
This method constructs a 2D NumPy array for the requested scattering
matrix data data for one or more energy groups and subdomains.
NOTE: The scattering moments are not multiplied by the :math:`(2l+1)/2`
prefactor in the expansion of the scattering source into Legendre
moments in the neutron transport equation.
Parameters
----------
in_groups : Iterable of Integral or 'all'
