Anomalous low-energy electron attachment in C_{60}
  We propose that thermal electron attachment to C$_{60}$ should occur preferentially in the p-wave channel, following an analysis of the vibron excitation spectrum of C$_{60}^-$. A very simple model based on this idea is shown to account very well for recent attachment data. The unexplained activation energy of $\approx$ 0.26 eV found experimentally is attributed to the p-wave centrifugal barrier.
