Tests of the methods of analysis of picosecond lifetimes and measurement of the half-life of the 569.6 keV level in 207Pb

Detection of single atoms and nuclei by methods of laser spectroscopy

“…The thin plastic scintillator measured the P+/Ec decay of I2"Cs feeding the levels of ""Xe (figure l), and the Si(Li) crystal detected the conversion electrons. Coincidences were set up between the two detectors and lifetime measurements were carried out by the centroid shift method[13]. The energy…”
