The number of states corresponding to a given energy plays a crucial role in atomic structure and thermodynamic properties. Determine the degeneracy of a body rotating with l = 4.

Solution

Solution:

The degeneracy is always 2l+1 because ml ranges from -l to +l in integer steps, including 0.

so for l=4,

dengeneracy = 2(4) + 1 =9
