Exclusive cross-sections and the thermodynamic model

The thermodynamic model was formulated to determine inclusive single particle spectra. A relationship with the second moment of the multiplicity was found for two-particle spectra. The authors consider two limiting cases of the relationship, the multiperipheral model and the diffractive excitation model. The formalism of generating functions allows the determination of exclusive cross-sections for both these models. An outline of the method is given. (7 refs).
