AN INTERPRETATION OF SOME POSTELECTROLYSIS NUCLEAR EFFECTS IN DEUTERATED TITANIUM

An explanation is proposed for the time dependence of the neutron emis sion transient observed after interrupting the electrolysis in Fleisch mann-Pons-type experiments with titanium cathodes. If is suggested tha t the time structure of the neutron emission is related to a reduction of active volume (i.e., the volume with a loading ratio higher than t he critical value necessary for cold fusion to take place) in the deut erated titanium. This reduction occurs during the postelectrolysis tim e due to deuterium transport from the TiDx delta-phase layer to the un deuterated bulk of the cathode. Calculations of the active volume decr ease are done by wing the Wagner model.
