AbstractAbstract
[en] This work consists in the development of a circuit to interface a photoacoustic spectrometer with a microcomputer. The obtained spectra are identical to those obtained in commercial photoacoustic spectrometers. The system permits a great versatility and it has possibilities to automatize other types of experiments. The system can be duplicated from national components and at a relatively low coast. (author)

AbstractAbstract
[en] The transition of surface plasmon which was optically excited by attenuated total reflection(ATR)method is investigated by using photoacoustic method. We made a new suggestion that the dispersion relation of surface plasmon can be obtained by means of photoacustic technique. The radiative quantum efficiencies of surface plasmon are measured for three different wavelengths of incident light. (Author)

AbstractAbstract
[en] A photoacoustical dosimeter (PARD) was developed which consists of a metal chamber with a small gas volume (circa. 1.cc) where the radiation to be detected impinges on a target. (E.G.)
