Notes The magnetic moment of an electron The magnetic moment of an electron is a fundamental property related to its spin and charge. It arises due to the electron’s intrinsic angular momentum, or spin.In the absence ...
Notes Winger Eckart Theorem The Winger-Eckart theorem is a fundamental result in the field of quantum mechanics and group theory, particularly in the context of molecular and atomic physics. It provides a way to ...
Notes Schrodinger equation for a system of two interacting particles Two particles system is obviously 6 dimensional problem. We can 6 dimensional problem to three dimensional problem by introducing relative and centre of mass coordinates.For two particles 1 and ...
Notes Screening doublet law The "screening doublet law" in X-ray spectroscopy refers to a specific empirical relationship observed in the energies of characteristic X-ray emission lines from elements. This law describes how the …
Notes Spin and screening dublets in X rays spectrum In X-ray spectroscopy, particularly in the context of inner-shell transitions within atoms, spin and screening dublets refer to specific features in the spectrum that arise due to the spin-orbit …
Notes Fine structure of X ray levels The "fine structure" of X-ray levels refers to the detailed characteristics and properties associated with the energy levels of X-rays. Here are some key points regarding the fine structure of ...
Notes Broadening of spectral line It has been observed that no strictly sharp spectral lines have been observed. It has a fixed width that depends on the reserving power of the optical instrument by which ...
Notes Paschen-Back effect The Paschen-Back effect refers to the splitting of spectral lines in the presence of a strong magnetic field, which causes the energy levels of atoms or ions to change. This ...
