HAMILTONIAN-FORMULATION FOR THE POSITRON TRAPPING MODEL - AN EXTENDEDTREATMENT

An extended treatment for the analysis of the two-state positron trapp ing model employing the Hamiltonian formulation is developed, the case of more than one kind of defects being also valid. The formalism is a pplied when the initial positron population decays into three states: bulk, vacancy-type defects and another kind of defects as vacancy clus ters, dislocations or jogs. This description is consistent with common trapping-model results available but, in particular, Hamilton's forma lism gives a basis for the extraction of physical information from the non-stationary components of the solutions.
