摘要：

The alpha decay of the neutron-deficient nuclide Te-105 was observed. The Cr-50(Ni-58,3n) reaction was used to produce Te-105 nuclei. The Te-105 residues were selected with the Argonne Fragment Mass Analyzer and implanted into a double-sided Si strip detector where their subsequent alpha decay was detected. An alpha-decay Q value of Q(alpha)=4900(50) keV and a half life of T-1/2=0.70(-0.17+0.25)mu s were measured for Te-105 and a reduced alpha-decay width of W-alpha=3.3(-1.7+2.1) was deduced. The decay properties of Te-105 are compared with those of heavier Te isotopes and theoretical predictions.
