High-resolution studies of a beam-sensitive, transition-metal-containing poly-yne have indicated an unusual beam damage mechanism which conforms to a random-hit model rather than to the more usual mechanism whereby damage is initiated at faults and crystal edges. We present details of the low-dose, high-resolution techniques used and propose a model for damage in this unusual polymer.
