We constructed a new coincidence apparatus with a live-timed bi-dimensional data acquisition system to the coincidence counting using a 4[π][β] pressurised proportional counter and a high purity germanium gamma-ray detector. This apparatus allowed plural gamma-gate sets in coincidence counting and simultaneous measurement of gamma-ray intensity. Therefore, the disintegration rates of usual sources could be determined quickly and accurately; furthermore, the standardisations of [152]Eu and [133]Ba which were difficult by coincidence counting could be attained by two-dimensional efficiency extrapolation. The apparatus was applied to the measurement of gamma-ray emission probability by utilising the effectiveness in simultaneous measurements of disintegration rate and gamma-ray intensity. Gamma-ray emission probability for [59]Fe was measured to demonstrate the effectiveness and then the emission probabilities of gamma-rays for [86]Rb, [103]Ru and [42]K were measured. The certainty of the results came up to our expectations.
