摘要：

The Be 1s core level photoemission line from metallic Be is shown to contain unexpected internal fine structure. We argue that this line structure is caused by intrinsic excitation of a narrow band of optical phonons in the Is photoemission process. The general importance of the present results for high resolution core level photoemission investigations of metals is pointed out.
