Pauli’s Spin Formalism and Parity of Nuclei are discussed

in this video lecture. Pauli’s spin operator is defined in terms of the

spin vector. Further Spin operator components is defined in terms of

matrices of 2×2 rank. Pauli’s spinor that defines the spin state of the

particle in terms of the one column matrices. Alpha and beta are the

symbols for that. The Pauli’s operator when operates on the spinor gives

important results and some other basic properties of the operators are analyzed here.
