Information × Registration Number 0212U005240, 0107U005724 , R & D reports Title Production of total and partial cross sections at the intermediate energy using the filter beams of reactor popup.stage_title Head Gritzay Olena Oleksandrivna, Кандидат фізико-математичних наук Registration Date 11-04-2012 Organization Institute For Nuclear Research Of National Academy Of Sciences Of Ukraine popup.description2 The main aim: - investigation of nuclear physics properties of atomic nuclei at KR, particularly at neutron filtered beams; - modernization of existing and adoption of new experimental and calculation methods and experimental installations at reactor HECs; - modernization of information base, needed for compilation of experimental results into IBND and modelling the experiments at KR; - development of specialized nuclear data libraries for evaluation and calculation of radioactive isotopes yields at the irradiation in reactor neutron flux. Methods and instruments for investigations: - method for production of total neutron cross sections by measurements of neutron transmissions of investigated samples; - neutron spectrometry using gas filled proportional counters; - code methods and calculation programmes for calculation of neutron cross sections and develoment of specialized libraries. The main results: - installation for neutron beam intensity scanning in space was developed and realized in practice; - analysis was fulfilled about the possibility to use the method of neutron filtered beams to estimate the parameters of Carbon resonance at the energy about 150 keV; - analysis was fulfilled about the possibility to estimate the parameters of resonances using the method of average filter energy shift; - information and code bases for compilation of experimental resultsinto the IBND and modelling the experiments at KR were modernized; - specialized neutron data libraries for evaluation and calculation of radioactive isotope yields at the irradiation in reactor neutron flux were developed.
