Hi!

I want to calculate the density of states in the 3D, free electron gas, but I don't know how to do this.

Can somebody help me?

Thanks!

I just skimmed this, http://britneyspears.ac/physics/dos/dos.htm

Looks actually pretty good. They solve for 1D, 2D, and 3D.
 
Thanks for this answer!
 
To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
