摘要：
Double-beta decay from the ground state of Mo-100 to the 0+ excited state at 1130.29 keV in Ru-100 has been observed. A 956 g sample of molybdenum metal powder isotopically enriched to 98.468% Mo-100 was counted in a Marinelli geometry with a well-shielded, ultralow-background germanium detector. The cascade gamma-rays at 539.53 and 590.76 keV in Ru-100 were observed at the 99.998% confidence limit. The systematic errors have not yet been evaluated, but the data support a half-life of approximately 10(21) y.
