在ATOMKI的ECR离子源上产生并研究了富勒烯+铁（C60+Fe）混合等离子体。等离子体的两个主要成分是通过不同的灯丝烘箱获得的。在这一系列的测量中，我们集中在等离子体中C58（受损富勒烯）的最大比例上。C58比C60稳定性差，形成新材料的可能性更高。使用这种方法，我们产生了质量M=752的分子，它们都处于单电荷和双电荷状态，光束强度分别为8 · 10− 10 A和2 · 10− 10 A。我们确定该束为FeC58，O2C60和CO2C59的混合物，而实验没有给出铁和氧在碳球中的确切位置的信息。
Abstract Fullerene+iron (C60+Fe) mixture plasmas were produced and studied in the ECR ion source of ATOMKI. The two main components of the plasma were obtained by different filament ovens. In this series of measurements we concentrated on the maximum ratio of C58 (damaged fullerene) in the plasma. C58 is less stable than C60 and the probability to form new materials is higher. Using this method we produced molecules of mass M=752 both in single‐ and double‐charged states with beam intensities of 8 · 10−10A and 2 · 10−10A, respectively. We identified this beam as a mixture of FeC58, O2C60 and CO2C59, while the experiment did not give information on the exact location of the iron and oxygen in the carbon ball.
