  We consider the Gross-Pitaevskii(GP) model of a Bose-Einstein Condensate(BEC)
for single-component and multi-component BEC. The pseudopotential for s-wave
scattering between atoms is taken to be of width of the order of the s-wave
scattering length. Such an interaction giving rise to a roton minimum in the
spectrum of elementary excitations of a single component BEC is well known.
However, softening roton modes takes us in the strongly interacting BEC regime
where three body losses occur. We study the roton mode softening for a
multi-component BEC. We show that by increasing the number of components of a
multi-component BEC, the roton mode can be softened at a progressively lower
value of the gas parameter ($a^{3}n$), thus reducing three body losses.
