摘要

Nuclei in the light actinide region with Z 92，N 134 are predicted to be candidates for shape coexistence[1],some nuclei in this region are also predicted to have stable octupole deformation[2]. Actinide nuclei with N=134have been produced up to plutonium (228Pu), and the lightest plutonium isotope and neptunium isotope discoveredso far are 228Pu and 225Np respectively. A campaign has been started to investigate the nuclei in this region. Thereaction 20Ne + 209Bi was used to produce 224Np (N=131) in fusion-evaporation reaction as the first step.
