| Abstract: | Using properties of the inverses of annihilation and creation operators of f-oscillator we construct the f-analogues of squeezed vacuum states. If used to describe the motion of a trapped ion, the phase probability distributions of these states for large η are very different from those of the usual squeezed vacuum state. |
