The arrest process of a running crack meeting a small hole or arrest cylinder was studied by means of experimental and numerical methods. The results showed that velocity of the running crack increased when the crack approached a hole, but the velocity decreased rapidly when the running crack approa

✦ Synopsis
The structure of carbon cluster intermediates along the pathway of C6o formation is investigated. After laser evaporation, the carbon clusters are treated with hydrogen and analyzed by time-of-flight mass spectrometry. The different amount of ligands of the C clusters allows a determination of their structure. The results favour the model of fullerene formation by a naphthalenoctyl polymerization process published recently.
