Analysis of energy spectrum of neutrons in cold-fusion experiments by the TNCF model

The energy spectra of neutron in the cold-fusion phenomenon measured by Bressani et al. in a Ti/D gas loading system were analyzed with the TNCF (trapped neutron catalyzed fusion) model proposed by one of the authors (H. Kozima). The result shows that the data of positive results are interpreted consistently with a value of the adjustable parameter nn=104-107 cm-3. These values of nn are in the smallest range of values determined hitherto in various materials used in the cold-fusion experiments with positive results. A possible cause of the small value of the parameter nn is discussed taking into consideration the characteristics of the sample
