Phosphorus in C₆₀ — •Carola Meyer, M. Waiblinger, K. Lips, W. Harneit, and A. Weidinger — Hahn-Meitner-Institut Berlin

P@C₆₀ is a stable, endohedral Fullerene with the phosphorus atom caged nearly interactionfree inside the C₆₀ molecule keeping its atomic structure. For the very reactive phosphorus this is quite surprising. The atomic structure is shown in very sharp and definite Electron-Paramagnetic-Resonance (EPR) spectra. Spectroscopy of the solid state is very sensitive on deformations of the cage, which appear in the EPR spectra. Spinrelaxationtimes of phosphorus in C₆₀ are quit long compared to other paramagnetic materials, but significant shorter than the extremely long relaxationtimes in N@C₆₀.
