| 英文摘要 | In this study, Ac-218 and Th-221 nuclides were produced via the heavy-ion induced fusion evaporation reaction Ar-40 + W-186. Their decay properties were studied with the help of the gas-filled recoil spectrometer SHANS and a digital data acquisition system. The cross section ratio between Pa-222 and Ac-218 was extracted experimentally, with measured value 0.69(9). Two new possible alpha decay branches to Th-221 are suggested. The valence neutron configurations for the daughter Ra-217 are discussed in terms of the hindrance factors. |
