Electrons emitted in this manner can be called photoelectrons. BA = \frac{1}{2}[A, B]-\frac{1}{2}\{A, B\}.$$, $$ They also help to explain observations made in the experimentally. Is it possible to have a simultaneous eigenket of A, and A2 ? What is the physical meaning of anti-commutator in quantum mechanics? JavaScript is disabled. Pearson Higher Ed, 2014. Part of Springer Nature. If the same answer is obtained subtracting the two functions will equal zero and the two operators will commute.on.
