Editing Gadolinium (section)

===Niche and former applications===
Gadolinium is used for [[neutrino#antineutrinos|antineutrino]] detection in the Japanese [[Super-Kamiokande]] detector in order to sense [[supernova]] explosions. Low-energy neutrons that arise from antineutrino absorption by protons in the detector's ultrapure water are captured by gadolinium nuclei, which subsequently emit [[gamma ray]]s that are detected as part of the antineutrino signature.<ref name="Abe 2022">{{cite journal | last1=Abe | first1=K. | last2=Bronner | first2=C. | last3=Hayato | display-authors=etal | title=First gadolinium loading to Super-Kamiokande | journal=Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment | volume=1027 | year=2022 | issn=0168-9002 | doi=10.1016/j.nima.2021.166248 | page=166248| arxiv=2109.00360 | bibcode=2022NIMPA102766248A | s2cid=237372721 }}</ref>
