利用广东科学研究院UNILAC加速器的208Pb束，我们产生了新的同位素203Au和205Au，并通过测量它们的β衰变特性对它们进行了鉴定。它们的半衰期分别为60(6)S和31(2)S，并确定203Au的Q值为β=2040(60)keV。从这个测量中得到了203,205汞的核结构信息。此外，还给出了203205Au的产生截面，并与其他实验得到的结果进行了比较。
Using a208Pb beam of the UNILAC accelerator at GSI we produced the new isotopes203Au and205Au and identified them by measuring theirβ-decay properties. Their half-lives were found to be 60(6)s and 31(2)s, respectively, and theQ-value of203Au was determined to beQβ=2040(60)keV. Nuclear structure information of203,205Hg was derived from this measurement. Furthermore, production cross-sections of203,205Au are given and compared to those obtained in other experiments.
