Liquid Helium - Fermi Temperature

[mathtrek]

Hi all,

I'm working out various Fermi Temperatures of substances (potassium, neutrons in a neutron star etc) and have come to Liquid 3He (density 81kgm-3). I've been told that these are not electrons when considering liquid Helium, but I'm at a loss of how to proceed. Has anyone got any ideas?

 

Thanks!

liquid helium exhibits 0 viscosity. they are superfluids and I think they are in the form of condensates--maybe bose-einstein condensates
