    Sammanfattning : The study is based on data collected at the LEP II accelerator during the second period of the Large Electron-Positron collider operations (1996-2000). During that time the DELPHI (DEtector with Lepton, Photon and Hadron Identification) experiment collected about 90 Gb of data on tape corresponding to 687-691 pb-1 of luminosity. LÄS MER

  7. 5. Some studies in nuclear structure by coincidence measurements

    Författare :Benny Sundström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The coincidence technique is a basic method for determining nuclear parameters.From single and coincidence gamma-ray measurements, using high resolution Ge(Li) detectors, a level scheme of 123Sb was determined. LÄS MER
