  Two-magnon Raman scattering intensity is obtained for two-dimensional
spin-1/2 antiferromagnets in presence of hopping disorder. A consistent mode
assignment scheme is prescribed which essentially establishes a correspondence
between the hopping-disordered and the pure system. It is seen that a minute
amount of disorder in hopping leads to a good agreement of the Raman lineshape
experimentally obtained for the copper-oxide insulators such as ${\rm
{La_{2}CuO_{4}}}$. Also it is observed that a considerable asymmetry with
respect to the two-magnon peak appears and the spectral intensity persisting
much beyond $4J$ (where the joint magnon density of states peaks). This has
been argued earlier by us [S. Basu and A. Singh, Phys. Rev. B, {\bf {53}}, 6406
(1996)] to be arising due to highly asymmetric magnon-energy renormalization
because of a cooperative effect arising from local correlation in hopping
disorder.
