The emission probabilities for the γ-rays of <SUP>75</SUP>Ge were accurately measured by a 4πβ counter, a high purity germanium γ-ray detector and a coincidence apparatus using a live-timed bi-dimensional data acquisition system. Two series of measurements were carried out ; in the first a 4πβ counter with pressurized Ar 90% plus CH<SUB>4</SUB> 10% mixture was used, and in the second that with CF<SUB>4</SUB> gas at atmospheric pressure was used. The emission probability of the main 265 keV γ-rays was 0.1020±0.0017, that was smaller than the evaluated value, 0.113±0.011 (Nucl. Data Sheets, 1981), by about 10%, and the certainty was improved by about six times.
