测量了银和金薄膜从200 mµ到1，200 mµ的光谱透射率。结果表明，加热后的银膜在435 mµ ~ 480 mµ处出现强烈的共振吸收，随后导带电子吸收消失。对于加热的金膜，也得到了类似的结果，但吸收强度相当弱，峰位移动到510 mµ-550 mµ。在考虑二维聚集体的情况下，从导电电子在构成薄膜的金属微粒中集体运动的观点进行了讨论。
The spectral transmission from 200 mµ to 1,200 mµ of silver and gold thin films was measured. It was found that for heated silver films a strong resonance type absorption appeared with the peak at 435 mµ ∼ 480 mµ and then the absorption due to electrons in the conduction band disappeared. For heated gold films, the similar results were also obtained but the absorption strength was rather weak and the peak position shifted to 510 mµ ∼ 550 mµ. By taking into account the two dimensional aggregations, some discussions were made from the view point of the collective motion of conduction electrons within small metallic particles of which the film was composed.
