===Elastic scattering===
[[Electron scattering]] off of a proton can change it to a Λ and produce a K<sup>+</sup>:{{sfn|Gal|Hungerford|Millener|2016|p=12}}
:p + e<sup>−</sup> → Λ + e<sup>−</sup>{{prime}} + K<sup>+</sup>
where the prime symbol denotes a scattered electron. The energy of an electron beam can be more easily tuned than pion or kaon beams, making it easier to measure and calibrate hypernuclear energy levels.{{sfn|Gal|Hungerford|Millener|2016|p=12}} Initially theoretically predicted in the 1980s, this method was first used experimentally in the early 2000s.<ref>{{cite journal |last1=Nakamura |first1=Satoshi N. |last2=Fujii |first2=Yuu |last3=Tsukada |first3=Kyo |title=Precision spectroscopy of lambda hypernuclei using electron beams |journal=Nippon Butsuri Gakkai-Shi |date=2013 |volume=68 |issue=9 |pages=584–592 |url=https://inis.iaea.org/search/searchsinglerecord.aspx?recordsFor=SingleRecord&RN=45008322 |issn=0029-0181}}</ref>
