摘要
Muon capture isotope detection (MuCID) is a non-destructive detection (assay) of composite and impurity nuclear isotopes by measuring gamma rays following muon capture reaction products. Several nuclear isotopes are produced by muon capture reactions such as (mu, xn gamma) with x = 0, 1, 2, 3, and so on, and some of them are radioactive isotopes. The isotopes of the interest are identified by measuring gamma rays characteristic of the reaction products by means of high-sensitivity Ge detectors. Composite and impurity nuclear isotopes of the orders of microgram-nanogram and ppm-ppb are investigated. The feasibility and the sensitivity of MuCID were shown experimentally by using mu capture reactions on Mo isotopes at MuSIC in RCNP. MuCID is used to study nuclear isotopes of astro-nuclear and particle physics interests and those of geological and historical interests.
