The components of the vector denoted alpha in the Dirac Hamiltonian are conventionally expressed in terms of this quantity's operators.
The components of the vector denoted alpha in the Dirac Hamiltonian are conventionally expressed in terms of this quantity's operators. By definition, pseudoscalar mesons and vector mesons have different values of this quantity. Whether a wavefunction is symmetric or antisymmetric with regard to the exchange of two particles is given by a theorem named for this quantity and the word "statistics." The operators of this quantity are equal to (*) h-bar over 2 times a set of three Hermitian 2 by 2 matrices named for Pauli. Triplet and singlet states have different values for this quantity. This quantity is added to the orbital angular momentum to give the total angular momentum. For 10 points, the fourth quantum number represents what quantity, which for an electron equals plus or minus one-half?
