Sied Mehdi Fakhraie,Kenneth Carless Smithdefine stationary states which correspond to definite energy levels of the atom. We have already seen that according to Heisenberg’s uncertainty principle Δ.Δ.⩾.,where Δ., Δ. are the uncertainties in measuring energy and time respectively. If the energy is known exactly, then Δ.→0 and therefore Δ.→∞

In conditions of coherent resonant interaction, the transfer of energy between radiation and matter is reversible, but

Many excited states of such nuclei can be studied in this way, and a particularly interesting class of states is those composed of a linear chain of alpha-particles, some of which have been identified experimentally.

If it is supposed that each circular orbit must contain an integral number of waves as shown in Fig. 10.1, it becomes clear that only orbits of certain radii are possible. Expressed quantitatively this means that . = ., where . is the radius of the circle and . is an inte
