Development of general nuclear resonance fluorescence model

Ogawa, Tatsuhiko; Hashimoto, Shintaro; Sato, Tatsuhiko

Nuclear resonance fluorescence (NRF) is regarded as a useful phenomenon for application to non-destructive assay of fissile nuclei because NRF cross section peak energy is specific to isotopic species and detection system can be build using conventional photon detectors. So far, experimental technique such as monochromatic photon source based on inverse Compton scattering are intensively studied. In contrast, some unofficial release of nuclear reaction models to simulate NRF based on the literature data are available; however, no general-purpose NRF model was developed. In this study, general-purpose NRF model which can simulate NRF of 1071 nuclear species including unstable nuclei from Li to Bk was developed using nuclear structure data of ENSDF (Evaluated Nuclear Structure Data File) and theoretical description of the level transitions. Moreover, the model was applied for generation of radioactive nuclei and nuclear material assay to illustrate its effectiveness. This model was incorporated to PHITS ver.2.82 released Dec. 25th 2015 and provided to users.
