Query: 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.
