The technique of passing two heavy nuclei very close to one another at nearly the speed of light allows for photons, arising from the electromagnetic field of each nucleus, to interact with the other nucleus, occasionally forming a rho particle that decays into two pions. When both nuclei do this at once, the entanglement can be seen, and the radius of the atomic nucleus can be measured.<\/p>\n<p>It\u2019s also remarkable that measuring the size of the nucleus through this method, which uses the strong force rather than the electromagnetic force, gives a different, larger result than one would get by using the nuclear charge radius.
