✦ Synopsis

The gamma-ray emission probability per decay for the 1266-keV transition of "Si has been measured. This radionuclide was obtained by means of the "P(n,p)"Si reaction in a fast neutron flux at the IPEN 2 MW research reactor. The sample activity has been measured by the 4t$-y coincidence method and the efficiency tracing technique was applied using "Na as the tracer. The gamma-ray counting has been performed in a calibrated HPGe spectrometer.

The resulting emission probability per decay obtained for "Si was 5.537 x 10m4 with an overall error of 1.21% (one standard deviation).

The emission probabilities for the y-rays of "'Yb were accurately measured by a 4njl @PC)-y (HPGe) coincidence apparatus using a live-timed bi-dimensional data acquisition system. The emission probability of the main 396 keV y-rays was 0.1315 & 0.0016, a value that was about twice the evaluated valu
