Spectroscopic Study of Mid-Weight Nuclei with Emphasis on Angular Distributions
Summary:
The reaction 112Cd(p,γ)113In was studied at four proton beam energies partly inside the Gamow window Ep=2.8, 3.0, 3.2, 3.4 MeV. The purpose of the experiment was to study the total cross section and the angular distribution of the de-exciting nuclei. The measurements were carried out at the 5.5 MV T11 Van de Graaff Tandem accelerator of the Institute of Nuclear Physics of the National Center for Scientific Research (NCSR) “Demokritos”. Four HPGe detectors were placed on a motor-driven table that could rotate. This way, gamma spectra were measured at eight angles with respect to the beam direction. At each angle, two different gamma spectra per detector were taken. We used a thin target of 112Cd (1.2 mg/cm2) and total cross sections were obtained via the subsequent data analysis for the in-beam method. The resulting cross sections were compared to Hauser-Feshbach calculations using the code TALYS.
