The angular distributions of neutral pi mesons produced in hydrogen by gamma quanta with energies lying between the threshold and 240 Mev were investigated. The energy dependence of photoproduction was studied bv employing the method of multichannel analysis of the data of the monitor and counters recording single decay gamma quanta in an expanded synchrotron pulse. The angular distribution of the pi /sup o/ mesons in the c.m.s. has the form which signifies photoproduction of neutral pi mesons not only in the P but also in the S state. The experimental data on the contribution of the S state agree with the results of the calculations presented earlier and perinit one to estimate the contribution of direct pi /sup o/ meson photoprnduction processes and intranucleon charge exchange'' of pi /sup +/ mesons in the S state.
