Slater determinants are the simplest wavefunctions that satisfy this statement. For 10 points each:
[10m] Name this statement that applies to particles with half-integer spin. A consequence of this statement is that electrons in the same orbital must have opposite spins.
ANSWER: Pauli exclusion principle [or Pauli principle; prompt on PEP]
[10h] The Pauli principle implies that if the principal, magnetic, and spin quantum numbers of electrons in an atom are the same, this number is different. This quantum number denoted by a lowercase l determines the subshell.
ANSWER: azimuthal quantum number [or angular momentum quantum number]
[10e] The Pauli principle explains why the value of this quantity for an electron gas in a white dwarf is non-zero. This quantity is measured in pascals and equals force divided by area.
ANSWER: pressure [accept electron degeneracy pressure]
