Chapter 7, Problem 7C.4P

Interpretation Introduction

Interpretation:

Whether the operator corresponding to angular momentum of a particle, $\left(\hslash /i\right)\text{d}/\text{d}\varphi$ is hermitian has to be shown.

Concept Introduction:

Hermitian operators are those for which the relation ${\displaystyle \int {\psi }_i^{*}}\widehat{\Omega }{\psi }_{j}d\tau =\left\{{\displaystyle \int {\psi }_j^{*}\widehat{\Omega }{\psi }_{i}d\tau }\right\}$ is true.  All the quantum operators corresponding to observables are hermitian.
