M050300100015 ERR-ANALYS (ERR-S) All statistical errors due to positron M050300100016 induced events, electron induced events, and M050300100017 efficiency measurements are given. M050300100018 (ERR-SYS,,15.) The systematic error, arising from the M050300100019 photon flux calibration and detector efficiency M050300100020 determination, is less than 15 %. M050300100021 STATUS (CURVE) Data were prepared in the MSU INP CDFE by M050300100022 V.V.Varlamov. M050300100023 COMMENT Absolute photofission cross sections of U-235 and M050300100024 U-238 have been measured with quasimonoenergetic M050300100025 photons from e+ annihilation and direct fragment M050300100026 detection between 11.5 and 30 MeV.
