摘要：

Doppler broadened gamma spectra from positron annihilations in alumina and several zeolites were measured as a function of internal surfaces. In all cases, the gamma line shape parameter was found to vary proportionally with surface area. The results greatly enhance the potential of using positron annihilation spectroscopy as a microprobe for surface studies of porous materials.
