Superfluid helium and spin

  • #1

Main Question or Discussion Point

In a superfluid a small volume of liquid can be considered to behave as a single particle.Does this mean that ,for example,one cm^3 of helium-4 atoms
has a total spin of 2?

No it is not a single particle behavibour but a single fluid behavibour. The He-4 system is a many body system,
that exists in a superfliud state. The syetem is a fermionic system in which lambda transition takes place. The total spin is sum (i) spin (i) = S saturation spin.
