Abstract

The spinning period for a free electron and the periods of spin and orbital motion of the electron in an atomic state have been calculated. We have shown that for a free electron the spinning period is: (T_s)_free=1.9×10^-20s. But in the atomic case we show that, both the spin and the orbital periods depend on the quantum numbers n, m_l, m_s and the effective Landé-g factor, g^* which is a function of the quantum number l of the atomic state given in Dirac notation. We have also calculated these periods for the ground state and some excited states—hydrogen and hydrogen-like atoms. For atomic states the approximate values of spinning period are and the related orbital periods are: (T₀)_atomic=(10^-16-10^-15)s. Therefore atto-second processes which are related to the pulse of 10^-18 s will filter the orbital motion of the electron but will be long enough to detect the details of the spin motion, such as flip-flops.
