The problem with α-decay is that Vmax is very large, and there is nowhere the α-particle could obtain so much energy within the nucleus. Where then does the energy come from? The quantum mechanical answer is that the particle does not ...

The quantum Hall effect is robust because it exists so long as there are edge states at opposite sides of the sample, which carry current in one direction only and are in separate equilibrium. The states on a single edge are chiral, that is, they pro ...

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.
