The α decay of the neutron-deficient nuclide 105Te was observed. The 50Cr(58Ni,3n) reaction was used to produce 105Te nuclei. The 105Te residues were selected with the Argonne Fragment Mass Analyzer and implanted into a double-sided Si strip detector where their subsequent α decay was detected. An α-decay Q value of Qα=4900(50) keV and a half life of T1/2=0.70(-0.17+0.25)μs were measured for 105Te and a reduced α-decay width of Wα=3.3(-1.7+2.1) was deduced. The decay properties of 105Te are compared with those of heavier Te isotopes and theoretical predictions.
