Erzeugung 21 neuer kurzlebiger Isomere durch Kernphotoreaktionen

摘要: Irradiation of 28 selected elements with 22.5 MeV bremsstrahlung led to the production numerous short-lived isomeric states by photonuclear reactions. At least 21 observed transitions seem not have been reported in literature thus far. The energies and half-lives were measured using a conventional scintillation spectrometer. newly discovered are region between 5·10−6 6·10−2 seconds. Isotopic assignments multipolarities yet established.
