摘　　要：Anomalous ^(3)He/^(4)He ratios in deuterium-loaded titanium samples are observed to be about 1-4×10^(-1),much greater than the values (≤10^(-4)) in natural objects.Control experiments with the deuterium-unloaded titanium sample and original industrial deuterium gas are also carried out,but no anomalous 3He/4He values are observed.In addition,anomalous tritium in deuterium-loaded titanium samples are also observed.To explain the excess 3He and tritium in the deuterium-loaded titanium samples,it is required that the deuteron-induced nuclear reaction occurs in the samples at low temperature.
