O154100100012 SAMPLE Self-supporting NiO target was used at EDE technique. O154100100013 The targets were prepared by oxidation of a 60-mug/ O154100100014 cm**2 Ni foil of natural isotopic composition. O154100100015 At TOF technique the targets consisted of self- O154100100016 supporting SiO(2) with a thickness of 50-mug/cm**2. O154100100017 FACILITY (VDGT,3ISLWZI) The tandem EN accelerator for the energyO154100100018 range E(lab)=27-42-MeV and O154100100019 (VDGT,2GERMPH) The 14-UD Pelletron accelerator for O154100100020 E(lab)=46-66 MeV. O154100100021 DETECTOR (TELES) O154100100022 Two monitor detectors were placed symmetrically with O154100100023 respect to the beam direction at angles of +-15 degree.O154100100024 CORRECTION *By authors*.Corrections for the simultaneous detectionO154100100025 of more than one photon were applied.

O154100100032 Pure random errors include the number of counts in the O154100100033 monitor detector and the reproducibility of the monitorO154100100034 system in different runs and is +-2%. The main O154100100035 additional source of error was the absolute X-ray O154100100036 intensities and the corrections for summing of O154100100037 coincidental radiations is 3%. O154100100038 A summation in quadrature of random and partially O154100100039 random errors yields a standard deviation of 8.4%. O154100100040 (ERR-1).The corresponding value for purely systematic O154100100041 errors is 3.2%. O154100100042 (ERR-T).By summing in quadrature the different sources O154100100043 of error (see above) adopted an error of 10% for each O154100100044 cross section was reported.
