Скачать или смотреть QMI(2022)1: Precession & Resonance - Electron in Magnetic Field (Prof. B. Aryal, TU / 30 March 2022)

Today I took my third successive lectures in last 3 days to the third semester, fourth semester and first semester students of M.Sc. (Physics). I discussed about the 'precession' and 'resonance' properties shown by the inherent property (intrinsic angular momentum) of electron when placed in external magnetic field (static & oscillating both). The spin precession is a quantum-mechanical effect. It describes an electron state when electron energy is between the spin-up and spin-down energy. The wave function of electron during the precession is intermixture of the wave function spin-down and spin-up state. Magnetic resonance, absorption or emission of electromagnetic radiation by electrons or atomic nuclei in response to the application of certain magnetic fields. The principles of magnetic resonance are applied in the laboratory to analyze the atomic and nuclear properties of matter.
