瑞典Lund大学科学家领导的一个国际团队确认了俄罗斯Dubna联合核研究所在2003年发现的115号元素。研究报告发表在《Physical Review Letters》上。新的超重元素具有高放射性，会在不到一秒时间内衰减成一个更轻的原子。研究人员通过用钙离子轰炸镅薄膜，测量与新元素α衰变有关的光子。新的元素尚未命名，其临时名称是Ununpentium，确认之后将会改名。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
