TGFs, known to be produced by lightning discharges since the 1990s, has been theoretically predicted to react with atmospheric nuclei via photonuclear reactions because they comprise high-energy photons of more than 10 MeV, but such photonuclear reactions by lightning discharges, which produce neutrons and unstable isotopes emitting positrons, were not observationally confirmed. The reactions and propagations of their products in the atmosphere are modeled with Monte Carlo simulations to quantitatively evaluate observations of TGFs, neutrons, and positrons at ground level. The successful comparison between observation and simulation is presented, and demonstrates that lightning discharges to trigger photonuclear reactions and to even produce isotopes in the atmosphere.. | | 出版日期 | Book 2021 | | 关键词 | High-Energy Atmospheric Physics; Lightning Discharge; Photonuclear Reaction; Terrestrial Gamma-Ray Flas | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-16-0459-1 | | isbn_softcover | 978-981-16-0461-4 | | isbn_ebook | 978-981-16-0459-1Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapor |
