MULTIPLE SPECIES OF POSITIVE IONS IN NORMAL LIQUID 3HE
The realization that ions of different size are produced in liquid 3He with different concentrations of 4He isotopic impurities has allowed researchers to select the ion to be studied just by changing the purity of the liquid. At about 70 mK, the positive ion mobility has a discontinuity related to the impossibility of further increase of an 4He-rich halo around the ion. Below the discontinuity, the temperature dependence of the mobility in the zero-field limit is well described by theory. At the discontinuity, it has been possible to determine the growth dynamics of the halo. The field dependence of the mobility also follows fairly accurately the theoretical description that takes into account ion recoil. The drift velocity non-linearities have put into evidence the equivalence of temperature and drift velocity in determining the ion mean energy.
