| Abstract | The isospin effect of particle emission for disassembling isotopic sources of Xe-122,Xe-129,Xe-137,Xe-146 and for isobaric sources of La-129, Xe-129, Sb-129 and Cd-129 are explored in the framework of the isospin-dependent lattice gas model. The multiplicity of emitted particles, the isotopic and isobaric ratios of light particles show the strong dependence on the isospin of the dissociation source, but the double ratios of light isotopes are insensitive to the isospin. The former directly reflects the chemical composition and the latter indicates the chemical equilibrium of the source. In addition, the slopes of the average multiplicities of emitted particles to temperature and the variances of the multiplicity distributions of emitted particles are suggested as additional judgements to the critical behaviour. The critical temperatures deduced from the above slopes and variances are found to be insensitive to the isospin of the disassembling sources. |
