On April 26, 1989, the Frascati Research Centre reported the emission of >5000 n/s over many hours from a titanium-deuterium system during changes of temperature and pressure. It was attempted to reproduce these observations using a highly sensitive (10%) thermal neutron monitor and two differently degassed titanium samples. During the 20-day experimental period, the neutron emission from these titanium-deuterium systems never exceeded 1.7 (first 8 days) and 0.6 n/s (last 12 days), averaged over 100-min intervals.
