C162900200008 METHOD (REC,TOF) The reaction yields (YToF) were extracted C162900200009 from time-of-flight histograms which were constructed C162900200010 with cuts on measured recoil-particle energy, C162900200011 specific energy loss (dE/dx), and gamma-ray energy. C162900200012 ANALYSIS The E1 cross sections were determined from the C162900200013 equation sigma E1 = YToF/(beta[1+(eff. E2/eff. C162900200014 E2)(sigma E2/sigma E1)]), where YToF is the peak C162900200015 yield from the time-of-flight spectra, and beta is C162900200016 the product of the number of incident particles, the C162900200017 number of target particles per square centimeter, the C162900200018 total E 1 detection efficiency, the CSF, and the C162900200019 detector live-time fraction.
