The simultaneous tritium and helium data obtained by Bockris' group in Texas A&M University are analyzed with the TNCF model. The adjustable parameter in the model is determined by the experimental data as n n =1.5x10 6 cm - 3 consistent with values determined for other events in the cold fusion phenomenon. To reconcile the data of tritium and 4 He, it is necessary to assume that only 1~10% of the generated 4 He remains in the surface region of the cathode where it has been observed.
