The Luonan Basin is a key region of early human settlement in Central China with more than 300 discovered Paleolithic sites. Artifact layer 1 of the Liuwan site was dated to approximately 0.6 million years (Ma) based ...
Because theαparticles’energy of 238Pu is similar with theα-nuclides of lead-bismuth eutectic(LBE)coolant,when the radioactivity is the same,their ability of exciting scintillation liquid to produce photons is equiv...
In recent years, extensive short-lived nuclear mass measurements have been carried out at the Heavy- Ion Research Facility （HIRFL） in Lanzhou using Isochronous Mass Spectrometry （IMS）. The obtained mass values hav...
