The proton Compton wavelength as the ‘quantum’ of length

Résumé

La plupart des longueurs expérimentales concernant les forces fondamentales dans le nucleus sont des multiples intégraux de la longueur d'onde Compton,λ0, du proton, oùλ0=h/m0c=1.32×10−13 cm (qui peut ainsi s'appeler un « compton »). Ces longueurs comprennent la portée effective des interactions des nucléons, et les amplitudes de dispersion.

On a également trouvé par différentes méthodes que le radius d'unité,R0, du nucleus se situe entre 1,0 et 1,5 × 10−13 cm. Il semble donc que le vrai radius du proton peut bien être sa longueur d'onde Compton.

    A fundamental length of the order of 10−13 cm was first postulated byW. Heisenberg, Ann. Phys.32, 20 (1938); Z. Phys.120, 513, 673 (1943). Of course, De Broglie wavelengths calculated for massive objects and high energy particles are very much smaller than this value, but their significance as physical lengths is certainly questionable.Google Scholar
