Describes an experiment in which a 500-A-thick silver film is evaporated on the hypotenuse face of a right glass prism. The surface plasmon mode in the film is excited with a He-Ne laser. The dispersion relation for the surface plasmon and the reflectivity due to the excitation of this mode are calculated. (Author/MLH)

Describes an experiment for determining the blackbody radiation constant hc/k, utilize a conventionally built cavity and a single-beam, single-window Perkin-Elmer 12-C model spectrometer. (SL)

Describes a technique in which blackbody radiation emitted or absorbed by a single microwave cavity mode is detected and displayed on an oscilloscope. (Author/CP)

Describes an experiment studying the decay of moth balls to demonstrate diffusion phenomena. (SL)

Describes an experiment to verify the Compton collision formula and the angular dependance of the Klein-Nishina formula. Equipment used is a 1-mCi(137)Cs source, 2x2 in. NaI detector and a multichannel analyzer. Suitable for honor undergraduates. (Author/GA)

Describes an experiment wherein simple gamma-ray detection and analysis techniques were utilized to study radioactivity in local precipitation. (Author/SL)

Describes the experimental arrangement for x-ray analysis of samples which involves the following: the radioisotopic x-ray disk source; a student-built fluorescence chamber; the energy dispersive x-ray detector, linear amplifier and bias supply; and a multichannel pulse height analyzer. (GS)

Experiments to measure range, range straggling, stopping power, and energy straggling of alpha particles are discussed in this article. Commercially available equipment with simple modifications is used for these measurements. (Author/GA)

Presents basic theory of silicon solar cells and discusses their use in experiments in undergraduate teaching laboratories. (SL)

Presents a dice-playing game which mathematically unsophisticated students and school children can play to learn empirically the principles of radioactive dating and population growth. (HM)
