摘要

Irradiation experiment was performed at the HIRFL-CSR in Lanzhou. A Pb foil with 100 mm diameter and0.15 mm thickness was used to measure the mass-yield distributions of induced radionuclides. A natural Pb cylinderwith 100 mm diameter and 250 mm length was used as the beam dump behind the Pb foil. An ionization chamberwas placed in front of the Pb foil to monitor the beam current. The carbon beam with an energy of 400 MeV/uwas stopped in the Pb cylinder after through the Pb foil. The irradiation was lasted about 20 h to make the beamfluence enough. After irradiation, the gamma spectra of Pb foil were measured by a off-line -spectrometry method.The measurements were performed by using a high-purity germanium (HPGe) detector.
