My first-author paper was published in Physical Review D

My new paper has been published in Physical Review D. The content is that the neutrons generated by the photonuclear reactions of lightning were directly detected by the GSO scintillator. Until now, neutrons generated by lightning have been indirectly detected by observing gamma rays emitted when they are captured mainly by nitrogen nuclei in the atmosphere. The GSO scintillator is an inorganic crystal scintillator composed of gadolinium, silicon, and oxygen, and is used in the hard X-ray detector of the X-ray astronomical satellite “Suzaku”. Gadolinium has a large cross-section for capturing neutrons, so it is used in Super-Kamiokande. This time, we demonstrated that this GSO scintillator can detect neutrons, and showed that it detected neutrons that actually reached the ground when lightning occurred.
