californium n.【化學】锎。

caliginous

At the first start up of a new reactor , primary source rods consisted of californium - 252 are inserted into the reactor to produce sufficient neutrons to initiate the first fission 反應堆在首次啟動時,會放入含有? - 252 ( cf - 252 )的一次中子源棒,以提供足夠數量的中子進行初次核裂變。

To create a mere three atoms of element 118 , the scientists spent two months bombarding the californium target with 30 billion billion calcium ions 為了創造這微不足道的3個原子,科學家花費了2個月時間,用30萬億億個鈣離子來轟擊锎離子。
