摘要：

Kinematical properties and chemical composition of vaporizing sources observed in heavy-ion collisions are presented. Vaporizing sources detected with the 4 pi array INDRA, are defined as sources for which all detected species have atomic numbers lower than 3. The excitation energy of the sources covers a very broad range (6-28 AMeV), The occurrence of thermodynamical equilibrium is discussed by comparing the data with the results of two statistical models, The model describing a gas in thermal and chemical equilibrium reproduces rather well the data suggesting that thermodynamical equilibrium may have been reached for such sources.
