Summary
Calculations have been made on the polarisation of protons scattered by nuclei at high energies. With the spin-orbit coupling similar to that used by E. Fermi one appears to get good agreement with experiments at 135 MeV. At 90 MeV phase-shifts were, for comparison, calculated both in the W. K. B. and the Born approximations. An alternative derivation of the explicit formula for the polarisation of neutrons first given by E. Fermi in the Born approximation is outlined briefly.
Riassunto
Sono stati eseguiti calcoli sulla polarizzazione dei protoni sparpagliati da nuclei ad energie elevate. Col termine di accoppiamento spin-orbita simile a quello usato daE. Fermi sembra si ottenga un buon accordo con l’esperienza a 135 MeV. A 90 MeV gli spostamenti di fase furono, per confronto, calcolati sia nella approssimazione W.K.B., sia in quella di Born. Si indica brevemente un’altra derivazione della formula esplicita per la polarizzazione dei neutroni data per primo daE. Fermi in approssimazione di Born.
