it has been shown that the boltzmann equation for the viscosity of the a-phase of superfluid 3he at low temperatures has the same form as for a normal ferrni liquid. the viscosity coefficients a, b, c, d and e are derived exactly. the h , parameter plays an important role in determining the temperature dependence of the viscosity coefficients

It is shown that the nuclear effects playing a relevant role in Deep Inelastic Scattering of polarized electrons by polarized 3He are mainly those arising from the effective proton and neutron polarizations generated by the S′ and D waves in 3He. A simple and reliable equation relating the neutron, g 1 , and 3He, g3 1 , spin structure functions is proposed. It is shown that the measurement of t...

Hyperpolarized noble gases are used in a variety of applications including medical diagnostic lung imaging, tests of fundamental symmetries, spin filters, atomic gyroscopes, and atomic magnetometers. Typically 3He is utilized because large 3He polarizations on the order of 80% can be achieved. This is accomplished by optically pumping an alkali vapour which polarizes a noble gas nucleus via spi...

2014 Magnetic diffraction in a bcc single crystal of 3He directly proves the occurrence of an antiferromagnetic ordering with a propagation vector ( 1 /2, 0, 0). J. Physique Lett. 46 (1985) L-923 L-927 ler OCTOBRE 1985, Classification Physics Abstracts 67. 80 75 . 25 75. 30E The originality of the magnetic ordering of solid 3 He is that the large zero point motion leads to atom-atom exchange pr...

Time reversal and parity non-invariant interactions within an atom naturally give rise to an atomic permanent electric dipole moment (PEDM). For noble gas atoms, the size of such a PEDM scales as Z 2 and higher powers of Z depending on the actual manifestation of T non-invariance, most importantly a distribution of electric dipole moment within the nucleus (Schiff Moment) and a T-odd tensor int...
