M025100100016 ERR-ANALYS (DATA-ERR) Root-mean-squared errors. M025100100017 COMMENT Neutron emission cross sections have been measured M025100100018 for targets of 6Li, 7Li, 10B, 14N, and 16O M025100100019 irradiated with x-rays in energy range from 7 to M025100100020 almost 30 MeV. M025100100021 The integrated cross sections are 0.40(0.03), M025100100022 0.49(0.04), 0.44(0.03), 0.42(0.03) and 0.26(0.02) in M025100100023 units of the classical dipole sum. M025100100024 The average cross sections for the lithium and boron M025100100025 targets appear to be essentially constant in the M025100100026 energy range 25-30 MeV. M025100100027 The data also suggest that the boron cross sections M025100100028 contains a great deal of structure up to the M025100100029 highest energies studied.
