Proof-of-principle demonstration of epithermal neutron resonance spectroscopy utilizing a compact laser–driven electron accelerator

Proceedings of the National Academy of Sciences, Volume 122, Issue 40, October 2025. <br/>SignificanceEpithermal neutron resonance spectroscopy has been limited by bulky spallation and accelerator-based sources, hindering on-site nuclear material analysis. This study employs a compact laser–driven electron accelerator to generate photonuclear …
