摘要：

We have measured the electron-capture decay branch of Tc-100 to be (1.8 +/- 0.9) X 10(-3)%, from which we deduce log ft = 4.4(+0.18/-0.30). This indicates that a two-step process connecting only the ground states of Mo-100-Tc-100-Ru-100 Can account for the measured 2nu double-beta-decay rate of Mo-100.
