摘要：

This report presents spectroscopic probes of intercalation processes in single walled carbon nanotubes. Before saturation doping of alkali metals (KCx, x similar to9), we found a rather stable intermediate phase KC27, where the Raman active E-2g mode shows an anomalous hardening. Considering the close correlation with the graphite intercalation compounds, we postulate that in KC,, phase, alkali ions are inserted between two tubes rather than the hollow site surrounded by three tubes.
