Experimental search for 'cold fusion' in the deuterium-titanium system

A series of experiments have been carried out to try and detect 'cold fusion' in titanium which has been loaded with deuterium at high pressure. No neutrons were detected using a range of counting systems, the most sensitive of which could detect 0.9 neutrons/s if sustained over 100 s. Bursts of more than 30 neutrons occurring in a period of less than 0.1 s could also have been detected using coincidence counting. Evidence for erratic behaviour of proportional counters, which could be mistaken for neutron emission, is presented.
