# Degeneracy Parameter A

When calculating whether Boltzmann, Bose-Einstein, or Fermi Dirac should be used there is an equation for Degeneracy Parameter A which can be initially used.

Degeneracy Parameter A = (N/V) (h^2 / 2 TT m k T)^(3/2)

What is represented by N and V and k?

Is N the Number Density, V Volume and k Boltzmann constant?

Thank you.

N is the total number of particles, so N/V is the number density. k is Boltzmann constant, h Plank constant ,m mass of the particles and T is temperature. I suppose "TT" should be a π (note the "Quick Symbols" on the right when writing a post).

Thanks very DrDu for clarifying that.

By TT I actually meant Pi. I notice now that ∏ is in the quick symbols.

Thanks again
