Abstract

Negative muons captured by atoms with zero nuclear spin usually retain about 1/6 of their initial spin polarization P0 after cascading down to their lowest Bohr orbital. This is particularly observed for μ- implanted into graphite and diamond. However, μ- implanted into a powder of the fullerene C60 are found to show essentially zero residual polarization. A residual polarization of ∼ P0/6 is again seen in metallic K3C60. We speculate that these results are to be explained on the basis of hyperfine effects after completion of the muonic cascade.
