| Abstract: | It is shown that the geometric phase appearing when the non stationary state evolves according to the cyclical or non cyclical Schrdinger equation. As an example, we calculate the geometric phases of the adiabatic state and the superposition of the adiabatic states for a spin 1/2 particle processing in a time dependent rotational magnetic field. |
