Abstract

The photoion yield curves for Dy@C₈₂^z+ (z = 1 and 2) from Dy@C₈₂ are measured by using synchrotron radiation in the photon energy range from 24.5 to 39.5 eV. Correction has been made to compensate the effect of transient change of the density of Dy@C₈₂ in the interaction region, with the help of the yield curve of C₆₀ ^z+ produced from C₆₀ remaining as a trace impurity in the sample. The yield of Dy@C₈₂⁺ exhibits a gradually descending curve with a flat region at 30-33 eV, similarly to the yield curve of C₆₀⁺ from C₆₀. The total photoabsorption cross section of Dy@C₈₂ was evaluated to be (1.2 ± 0.4) × 10^-20 m² at the photon energy of 39.5 eV.
