{\bf Measurement of inclusive $\bf \eta, \rho^0, f_0(980)$

\begin{abstract}
H1 results are presented on the inclusive photoproduction of the neutral 
mesons $\eta$, $\rho^0$, $f_0(980)$ and $f_2(1270)$ at an average
$\gamma{p}$ collision energy $W=210~GeV$. The measurement is based on
about $4\times10^6$ multihadronic events collected in the year 2000,
corresponding to an integrated luminosity of
$38.7$~pb$^{-1}$.

background using the measured like-sign spectrum.
The full curves show the result of a fit including the $\rho$, $f_0$ and
$f_2$ resonances. In the left plot 
the dashed curve corresponds to the contribution of residual non-resonant 
background, the dotted and dash-dotted curves describe the 
contributions from $\omega$ and $K^*$ reflections, respectively. 
In the right plot the points represent the data after subtraction of the
background and the reflections.}
