[爆卦] CERN將鉛變成金

中世紀煉金術士將鉛變成金的嘗試都失敗
CERN公布了大強子對撞機LHC中鉛衰變成金的測量結果
鉛原子核在大強子對撞機中鉛以光速的99.999993%與相鄰原子核擦肩而過
此過程會在原子核周圍產生超強電場並觸發光子-光子及光子-原子核的相互作用
這使得電磁場線被壓縮成垂直於運動方向的扁平狀並產生短暫的光子脈衝
造成原子核的少量中子和質子被彈出
此時若鉛原子核彈出三個質子就會變成金原子核
大強子對撞機在第二次運行時的四次主要實驗中共產生860億個金原子核
(總質量2.9*10^-11克)
第三輪產生的金原子核數量是第二輪兩倍
目前LHC的鉛-鉛碰撞每秒最多可產生89000個金原子核
但是當金原子核在下游各個點撞擊LHC光束管或準直器時就會分裂成質子、中子和其他粒子
數量不足以做成珠寶且只能存在一瞬間
研究結果改進了電磁解離的理論模型
這些模型有助於預測束流損失(對撞機性能的主要限制因素)
