Search for direct reaction products in 197Au+ 20Ne from 108 to 171 MeV projectile energy

The heavy ion induced nuclear reactions are of interest to nuclear physics community since long time. In this paper, we have reported production cross sections of 196Au, 198Au, 199Tl, 200Tl, 201Tl, which might be direct reaction (DIR) products, obtained through the interaction of 108-171 MeV 20Ne on natural gold target. The radioisotopes were identified and were quantitatively measured by off-line gamma spectrometry. We have also used two different simulation codes PACE4 and FLUKA (version 4-3.3). PACE4 did not predicted production of 196Au and 198Au, might be because PACE4 does not considers direct reactions, but predicted 199Tl, 200Tl, 201Tl. FLUKA grossly underpredicted production of all these radionuclides.

Calculation of true coincidence summing correction factor for a Broad Energy Germanium (BEGe) detector using standard and fabricated sources

The true coincidence summing (TCS) correction factor for a Broad Energy Germanium (BEGe) detector has been calculated at far and close geometry measurement using multi-energetic radioactive $\gamma$-ray sources $^{60}$Co, $^{133}$Ba and $^{152}$Eu. The correction factors were calculated using experimental method and analytical method. Photopeak efficiency and total efficiency required to calculate the correction factor were obtained using Geant4 Monte Carlo simulation code. A few standard as well as fabricated mono-energetic sources were also included in the $\gamma$-ray efficiency measurements. The simulated efficiencies of mono-energetic $\gamma$-ray sources were matched to experimental $\gamma$-ray efficiencies by optimizing the detector parameters. The same parameters were used to obtain the photopeak and total efficiency for $\gamma$-ray of our interest and coincident $\gamma$-ray. Analytical correction factors and experimental correction factors were found in good agreement with each other.
