... pump may transport different amounts of charge, since q is not a conserved quantity. It is the mean transferred charge that must be quantized. It appears to me that the criticism is rather sophistic, because if the average is an exact integer that does imply that every measurement gives an integer. ...

... Example: What is PF for the conduction electrons in gold? Solution: Again, using ρ = 58 nm–3, we find PF = 128 eV/nm3. The latter is not as directly informative as expressing PF in macroscopic units—i.e., converting eV to J and nm to m. When this is done we find PF = 2x1010 N/m2. As 1 atm = 105 N/m2 ...

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.
