  We study the approximate scattering state solutions of the
Duffin-Kemmer-Petiau equation (DKPE) and the spinless Salpeter equation (SSE)
with the Hellmann potential. The eigensolutions, scattering phase shifts,
partial-waves transitions and the total cross section for all the partial waves
are obtained and discussed. The dependence of partial-waves transitions on
total angular momentum number, angular momentum number, mass combination and
potential parameters were presented in the figures.
