任燕如 %A 尹道乐 %J 物理学报 %D 1981 %I %X By analysing the dielectric function of an interacting Bloch electron gas, the condition for the formation of acoustic plasmons (AP) as well-defined quasiparticles in metals has been derived. Discussions are given on whether this condition is satisfied for A-15 compounds, with the conclusion that the evidence for the existence of AP as a kind of quasiparticle in these compounds is insufficient until now. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=07F5D09CAB86725535866D80B13BDB1A&yid=AA64127AB7DEB65D&vid=340AC2BF8E7AB4FD&iid=E158A972A605785F&sid=6313C162FF75889A&eid=E5D85F291CED2DA6&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=0
