【大型强子对撞机“点铅成金”】5月15日讯，大型强子对撞机（LHC）大型离子对撞实验（ALICE）合作组让铅束“变身”为黄金。尽管这一过程仅持续了1微秒，而且成本高昂，但深入了解这一反应有助于改进粒子加速实验。相关研究成果发表于《物理评论快报》杂志。几个世纪以来，化学家们一直梦想将储量丰富的铅（质子数82）变为珍贵的黄金（质子数79）。如今，欧洲核子研究中心的科学家另辟蹊径：让铅离子束以接近光速对撞，在微观世界里实现了这个“点铅成金”的奇迹。ALICE合作组表示，虽然铅束对撞始终会产生微量金元素，但本次研究

Core Viewpoint - The Large Hadron Collider (LHC) has successfully transformed lead into gold through a high-energy collision process, providing insights that could enhance particle acceleration experiments [1] Group 1: Research and Development - The ALICE collaboration at CERN achieved a transformation of lead ions into gold, albeit for a duration of only 1 microsecond [1] - This groundbreaking research is published in the journal "Physical Review Letters" and represents a systematic capture and analysis of the reaction characteristics [1] Group 2: Scientific Significance - The experiment reflects a long-standing dream of chemists to convert abundant lead (with 82 protons) into precious gold (with 79 protons) [1] - The collision of lead ions at near-light speed in the microscopic realm has enabled this remarkable transformation, although it consistently produces only trace amounts of gold [1]
