Investigation of Iron‐Fullerene Mixture Plasmas in ECR Discharge

Abstract

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.
