The method is based on the common assumption that the stopping power is a linear decreasing function of the energy, in the energy range of interest in RBS, that is from 1.4 MeV to 2.0 MeV. The total yield can t
Branch isomersare a kind of structural isomer found in organic molecules (i.e., those that contain carbon). Carbon can bind to other carbon atoms in addition to bonding to hydrogen atoms, so once a carbon "chain" bordered by a hydrogen atom chain grows long enough for the atoms to move ...

In chemistry, a compound's valence number is the number of bonds formed by the electrons in the last (outer) shell (called valence electrons) of atoms to other atoms' valence electrons. The octet rule (the tendency of an atom to seek stability by filling its outer shell with eight electro...
A simple method is described for the determination of the number of atoms in a thin film from the integral of the elastic backscattering yield, using a pocket calculator. The energy dependence, E−2, of the Rutherford scattering cross section, and the screening of the nucleus charge by the...
