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: (Ts ) 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, m1, ms and the effective Lande-g factor, g* which is a function of the quantum number l of the atomic state ls ‹n, l, m1, ms› 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 (Ts)atomic ≅ 10-21 s and the related orbital periods are: (Ts)atomic = (10-16-10-15)s. Therefore atto-second processes which are related to the pulse of 10-18s 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.

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: (Ts ) 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, m1, ms and the effective Lande-g factor, g* which is a function of the quantum number l of the atomic state ls ‹n, l, m1, ms› 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 (Ts)atomic ≅ 10-21 s and the related orbital periods are: (Ts)atomic = (10-16-10-15)s. Therefore atto-second processes which are related to the pulse of 10-18s 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.
