Study of neutron-deutron reactions using a magnetic quadrupole triplet spectrometer
This work concerns the investigation of the final state interaction peak at the upper end of the proton energy spectrum at forward angles in the /sup 2/H(n,p)2n breakup reaction carried out at various incident neutron energies up to 25 MeV with good energy resolution. The scope of this work also includes the measurement of the anglular distribution of /sup 2/H(n,d)n elastic scattering and the simultaneous theoretical analysis of breakup and elastic scattering data with the main intention of testing their sensitivity to the value of n-n scattering length. A new magnetic quadrupole triplet spectrometer has been constructed at Ohio University to investigate neutron induced charged particle reactions, and the experimental aspect of this work mainly involves the testing and debugging of this device and its use in the measurements of n-d breakup and elastic scattering. The /sup 2/H(n,p)2n breakup was investigated at incident neutron energies of 11 and 25 MeV with energy resolutions of 175 and 300 keV, respectively, and mean proton angles of 2.5/sup 0/ and 3.0/sup 0/, respectively. A 0.82 mg/cm/sup 2/ thick deuterated polyethylene (CD/sub 2/) radiator was used in these experiments. The angular distributions of /sup 2/H(n,d)n elastic scattering were measured with 9 and 11 MeV neutrons from 0/sup 0/ to 45/sup 0/ and from 0/sup 0/ to 55/sup 0/, respectively, using a 3.0 mg/cm/sup 2/ CD/sub 2/ radiator. The data were analyzed to obtain experimental cross sections which were corrected for geometrical and systematic uncertainties. Theoretical calculations were performed on the basis of Faddeev three-body formalism using rank-one separable S and P-wave nucleon-nucleon interactions.
