Abstract
We therefore consider our assembly with a given energy or range of energies, to which there corresponds a large number of possible states, and have next to ask how such an assembly will behave according to the laws of quantum mechanics. If Schrodinger's equation which we have set up to describe the complete assembly were exact, and if it included exactly every interaction between the systems of the assembly and every interaction with walls and outside bodies, then in principle we could suppose it to be exactly solved and every eigen value and eigen function would then belong to a true stationary state in which the assembly (genuinely isolated) could persist for an indefinite time.The properties of the assembly would then be the properties of this single stationary state.Such a state of affairs however is never actually realizable even to the roughest approximation.In the first place we have neglected radiation and radiative processes in the formulation of Schrodinger's equation, and have assumed that all the interactions of the assembly with the external world can be represented by conservative forces.It is in principle impossible to represent the possible interactions with racliation by any time—independent conservative fields of force; nor can the action of the actual walls and external systems be represented by time—independent terms in the potential energy.The result of this is that it is impossible for a strictly conservative Schrodinger's equation to be set up, and the exact solutions, apparently possible in principle, are actually in practise illusory. ……
