摘要：

A model function for the lifetime analysis of slowly thermalising ortho-positronium is presented. Simulated spectra are analysed for a wide range of parameters and of statistical contents. A comparison with standard two-component analysis shows the power of the new model for specific problems. Experimental support in alumina fine particles is presented.
