“…Gamma spectra of the activation samples are measured with HPGe detectors, acquired by the Genie 2000 software (CANBERRA detectors) [17] or Maestro-32 (ORTEC detectors) [18] and analysed by the DEIMOS32 program [19]. Radionuclide production is analysed with an in-house gamma spectrometry package [20]. Radionuclide production is characterised by a quantity called Reaction Rate (R) which represents a number of nuclei generated in the activation foil normalised to a primary beam particle and the number of atoms of the activation foil.…”

The accelerator-Driven-System (ADS) is very important to study the neutron field and radionuclide production inside simple-geometry uranium subcritical setups irradiated with high energy particle beams. A subcritical setup QUINTA was irradiated with the 660-MeV proton beam from Phasotron accelerator at the Joint Institute for Nuclear Research (JINR). The radionuclide production in the region along the beam axis was investigated by the activation technique. The aim was to compare (n,x) with (p,x) reactions using activation detectors of 59Co and natPb, and compare experimental results with the calculated results using Monte Carlo simulation code MCNPX 2.7.

“…If the yield of a given isotope receives a contribution from the β − or the β + decay of neighboring unstable isobars, the respective calculation becomes more complicated [13,14]. If the formation probability for the parent isotope is known from experimental data or if it can be estimated on the basis of other sources, then the independent yields of daughter nuclei can be calculated by the relation…”

The yields of products originating from 238 U photofission are measured at the bremsstrahlung endpoint energies of 50 and 3500 MeV. Charge and mass distributions of fission fragments are obtained. Symmetric and asymmetric channels in 238 U photofission are singled out on the basis of the model of multimode fission. This decomposition makes it possible to estimate the contributions of various fission components and to calculate the fissilities of 238 U in the photon-energy regions under study.

The research deals with a spectrometry of neutron field based on the p(20)+Be source reaction. The p(20)+Be interaction stands for a nuclear reaction where protons accelerated to energy of 20 MeV bombard Be target. Produced neutron field has broad energy distribution up to 18 MeV. The research was carried out at the Nuclear Physics Institute of the Czech Academy of Sciences and was motivated by extension of experimental possibilities of the NG-2 target station. To determine the neutron spectrum, the activation foil technique was used. During the experiment, ten activation foils were irradiated. Activated foils were measured using the HPGe detector to determine the reaction rates of observed reactions. The neutron field was simulated in the MCNPX code, and the simulation served as a priori information for the unfolding of the neutron spectrum in the SAND-II code. A determined neutron spectrum is essential for various experiments, e.g., material research, measurements of nuclear data, etc.
