Proton size
2019年11月7日 — The team measured a proton radius of 0.84184 femtometres3. Randolf Pohl, who led that muonic hydrogen measurement and is now at the Johannes Gutenberg University in Mainz, Germany, has collaborated on other muonic experiments that have confi,2019年11月7日 — That means muon measurements of the proton's radius should be millions of times more precise than those made using ordinary hydrogen.
