Harmonic Mixing

We investigate the problem of distributing a given amount of heat among three systems under the following conditions: The systems are able to exhibit negative Kelvin temperatures, and heat equalization always fulfills a harmonic mixing rule T = 2T(1) · T(2)/(T(1) + T(2)). Just this happens for spin systems in the high temperature approximation.

High Temperature Approximation

The theory of the angular distribution of alpha particles and of fission fragments from nuclei aligned at low temperatures is presented. Very explicit results are obtained in the high temperature approximation. These are directly dependent upon the branching which takes place to the various allowed partial waves. This branching is influenced by the nuclear shape, but it is shown that for this problem the effect of penetrating a spheroidal barrier is not critical. An application is made to the experimental work so far available and the result is reasonably satisfactory.
