Abstract

Previous measurements1 of the positive ion mobility in liquid 3He below 1°K indicated the existence of a minimum with temperature; however, scatter and a hysteresis phenomena prevented a clear conclusion. A better measurement of this mobility is relevant as it should provide information on the structure of the positive ion in liquid He, a structure that is now under closer examination. Recent measurements by Johnson and Glaberson2 revealed the effect of various impurity ions on the mobility of these structures. According to the classical snowball model of Atkins,3 the minimum with temperature mentioned above is expected near 0.3°K as a consequence of the well-known minimum in the melting curve of 3He. In this work we suggest that the shape of the mobility minimum is related to the layered model proposed by Johnson and Glaberson.2
