The thought experiments are concerned with the behavior of two types of helium atoms, denoted³He and⁴He. These two types differ only in the nature of their nuclei. The³He nucleus contains two protons and one neutron, whereas the⁴He nucleus contains two protons and two neutrons.  4, record 1, English, - helium%2D4

L'hélium existe en deux isotopes : l'hélium-4 (⁴He) est l'isotope courant, représentant pratiquement 100% de l'hélium naturel. Son noyau comporte deux protons et deux neutrons (un nombre pair de nucléons) de sorte que l'atome est un boson.  1, record 1, French, - h%C3%A9lium%2D4

[...] dos clases de átomos de helio:³He y⁴He, que se distinguen por la naturaleza de sus núcleos. El núcleo de³He contiene dos protones y un neutrón; el de⁴He, dos protones y dos neutrones. Ambos núcleos poseen, pues, el mismo número de protones, lo que indica que presentarán la misma carga eléctrica.  1, record 1, Spanish, - 4He
