本文研究了超高真空中钾掺杂对反式聚乙炔光电子和亚稳猝灭谱的影响。我们发现钾的加入增强并移动了\ensuremath{\sigma}带峰，并在费米能级处产生了一个新的峰，该峰似乎起源于钾原子周围的轨道。
We study the modification of the photoelectron and metastable quenching spectra of trans-polyacetylene caused by doping with potassium in an ultrahigh-vacuum system. We find that the addition of potassium enhances and shifts the \ensuremath{\sigma}-band peak and creates a new peak at the Fermi level which seems to originate from an orbital localized around the potassium atoms.
