The energy levels of the heavy elements In, Sn+ and Sn are presented in this article. Dominating corrections beyond the relativistic Hartree-Fock method are included to all orders in the Coulomb interaction using the Feynman diagram technique and the correlation potential method.

Nanotechnology involves research and development on materials and species at length scales between 1 and 100 nm. The term nano is derived from the Greek word meaning “dwarf.” In dimensional scaling, nano refers to 10–9, i.e., one billionth of a unit. Thus, a nanometer is 10–9 m (0.000000001 m), or about the size of a molecule such as benzene. Nanotechnology therefore, refers to the techniques and methods for studying, designing, and fabricating things at the nanometer scale.
