据柏林理工大学的 Helmut Schwartz 和合作者称,C_(60)~+在质谱仪的氦气氛中加速,会生成(C_(60-n)H)~+离子,式中 n 为偶数。当使用氦-4时,离子比 C_(60-n)~+大
According to Helmut Schwartz and co-workers at the Technical University of Berlin, C_ (60) ~ + generates (C_ (60-n) H) + ions in a mass spectrometer helium atmosphere, where n is an even number. When helium-4 is used, ions are larger than C_ (60-n) ~ +
