✦ Synopsis

SHORT COMMUNICATIONS 0 (Lindemann) and the zero temperature lattice energy. The decrease zlG0 in the zero temperature thermodynamic potential Go of the electrons (Sommerfeld) is more important and corresponds with the energy difference involved in superconductivity. If A is the atomic weight:

The isotope effect may be derived. A modified distribution function gives the specific heat below the transition point. However, in this case the correction c~-cv is important. Thermodynamically the two-component system resembles the system ice-water. Some speculations may be made as to the normal transition temperature and the question what metals will become superconductive.
