ABSOLUTE CROSS-SECTION MEASUREMENTS FOR H AND D ELASTIC RECOIL USING 1 TO 2.5 MEV HE-4 IONS, AND FOR THE C-12(D,P)C-13 AND O-16(D,P)O-17 NUCLEAR-REACTIONS

Absolute differential cross sections dsigma(H)/dOMEGA and dsigma(D)/dOMEGA for elastic recoil of H and D using 1 to 2.5 MeV He-4 ions have been measured at 10-degrees, 20-degrees and 30-degrees laboratory scattering angles, with accuracies of +/-4 to 7% for dsigma(D)/dOMEGA, and +/-6 to 9.5% for dsigma(H)/dOMEGA, depending on the geometry; their ratios (dsigma(H)/dOMEGA)/(dsigma(D)/dOMEGA) have been measured to +/-2% in the same energy range and geometries. Cross sections for several nuclear reactions of interest in materials science have also been measured. at scattering angle theta(lab) = 150-degrees. That of C-12(d,p)C-13 at 968 keV is dsigma(C)/dOMEGA = 29.5+/-1.2 mb/sr; that of D(d,p)T in the same conditions is 8.6+/-0.5 mb/sr; that of O-16(d,p1)O-17 at 857 keV is dsigma(O)/dOMEGA = 5.3+/-0.4 mb/sr. The latter value was deduced from a measurement of the ratio R(C/O) = (dsigma(C)/dOMEGA)968 keV/(dsigma(O)/dOMEGA)857 keV = 5.56+/-5%.
