Popis: The elastic photoproduction cross sections for $\ensuremath{\rho}$ and $\ensuremath{\phi}$ mesons from protons have been measured from 30 to 180 GeV. The energy dependences agree well with predictions made by using vector-meson dominance and an additive quark model. The $\ensuremath{\rho}$ cross section is approximately constant with energy while the $\ensuremath{\phi}$ cross section rises from 0.5 to 0.7 \ensuremath{\mu}b with increasing energy.
