Summary

The spin lattice relaxation timeT1 has been measured in liquid3He from 1.1 to 3 °K at its saturated pressure. The results indicated a sharp increase ofT1 decreasing the temperature below 1.4 °K. This behaviour cannot be accounted for by the Bloembergen, Purcell and Pound theory.

Riassunto

Si è misurato il tempo di rilassamento spin reticoloT1 nel3He liquido fra le temperature 1.1 °K e 3 °K sotto la tensione di vapore saturo. Le misure indicano una rapida salita diT1 al diminuire della temperatura sotto 1.4 °K. Questo risultato non è in accordo con la teoria di Bloembergen, Purcell e Pound.
