متن کاملConditions for Isoscaling in Nuclear Reactions
Isoscaling, where ratios of isotopes emitted from two reactions exhibit an exponential dependence on the neutron and proton number of the isotope, has been observed over a variety of reactions including evaporation, strongly damped binary collision, and multifragmentation. The conditions for isoscaling to occur as well as the conditions when isoscaling fails are investigated. Typeset using REVTEX

متن کاملIsoscaling bearing information on the nuclear caloric curve
We show that the qualitative behavior of the nuclear caloric curve can be inferred from the energy dependence of the isoscaling parameters. Since there are strong indications that the latter are not distorted by the secondary decay of primary hot fragments, in contrast to other observables, this suggests that valuable information on the nuclear caloric curve may be obtained through the analysis...
متن کاملIsoscaling in statistical models
Different statistical multifragmentation models have been used to study isoscaling, i.e., the factorization of the isotope ratios from two reactions, into fugacity terms of proton and neutron number, R21(N ,Z) 5Y 2(N ,Z)/Y 1(N ,Z)5C exp(aN1bZ). Even though the primary isotope distributions are quite different from the final distributions due to evaporation from the excited fragments, the values...
