Within the ` = 2 states, we must have b ≤ 4, otherwise Lb+ simply annihilates all the states, as there is no level which can be raised more than 4 times. Now whatever b is, after acting b times on a state, the Lz eigenvalue must be at least −2 + b. ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
