Rezumat:

For the pseudoharmonical oscillator we have built the creation and
annihilation operators and the corresponding coherent states. After
the deduction of the density operator expression in coherent-state rep-
resentation in two ways (by their definition and by solving the Bloch
equation), we have calculated the expected values of some character-
istical physical observables.
