摘要：

We report the ejection of atoms at a crystal surface caused by energetic breathers which have travelled more than 10(7) unit cells in atomic chain directions. The breathers were created by bombardment of a crystal face with heavy ions. This effect was observed at 300K in the layered crystal muscovite, which has linear chains of atoms for which the surrounding lattice has C(2) symmetry. The experimental techniques described could be used to study breathers in other materials and configurations. Copyright (c) EPLA, 2007.
