Theoretical calculation of photoneutron reactions cross sections ((g,n), ((g,n)+(g,n+p)) and (g,abs)) for some alkali and alkaline earth elements

Photonuclear reaction data are very important for basic and applied researchs. Radiation shielding design, radiation transport analysis, activation analysis, astrophysical nucleosynthesis, safe guards and inspection technologies, human body radiotherapy absorbed dose calculations, beam monitoring in heavy-ion dissociation at ultra relativistic energies, radioactive ion beam or neutron production, waste transmutation and detection of nuclear materials and etc., can be mentioned. But there are discrepancies in both shapes and magnitutes between photonuclear cross sections measured in various laboratories (for example, CEA (Saclay), LLNL (Livermore) etc.). These discrepancies reduce the accuracy and reliability of data. Various types of data contained in the international data base (EXFOR) is given systematically.This study contains calculations of (g,n), ((g,n)+(g,n+p)) and (g,abs) reactions for 7Li, 9Be, 23Na, 24, 25, 26Mg, 39K, 40, 42, 44, 48Ca, 85, 87Rb, 84, 86, 87, 88Sr, 133Cs, 130, 132, 134, 136, 138Ba nuclei induced with 0 ? 200 MeV energy photons by using TALYS 1.2 code program.The calculated cross sections were compared with both the experimental data of cross sections and the evaluated cross sections in literature. And it has been shown that they are consistent.
