Precise measurement of the <sup>7</sup>Be electron capture decay half-life in silicon carbide
Abstract In this work we present to our knowledge the most precise measurement of the 7 Be electron capture decay half-life in a host material. A silicon carbide sample with ~8.62 × 10 9 7 Be atoms was measured for 83.5 d on an ultra-low background high purity Ge detector located deep underground in the Laboratori Nazionali del Gran Sasso, Italy. The result obtained for the decay half-life is T 1/2 = 53.284 ± 0.016 d, which corresponds to an uncertainty of 0.3‰. Thanks to the high sensitivity achieved, this measurement is paving the way to further investigations on this process aiming to understand how environmental conditions may affect the decay half-life.
