In general, this rule applies to half-spin particles called fermions meaning two particles can occupy the same region if and only if they have opposing (*) spins.
The term raised to the negative twelfth power in the Lennard-Jones potential accounts for this rule. White dwarfs exhibit electron degeneracy pressure, a factor limiting how much they can compress based on this rule. In general, this rule applies to half-spin particles called fermions meaning two particles can occupy the same region if and only if they have opposing (*) spins. For 10 points, name this rule of quantum mechanics typically stated as no two electrons can have the same four quantum numbers.
The term raised to the negative twelfth power in the Lennard-Jones potential accounts for this rule.
