Temperature ratio RT = TL/TH of fully accelerated complementary fragments (used for TXE partition) obtained independently of prompt emission model calculations
Several refined prompt emission model codes, nowadays employed, use the partition of total excitation energy (TXE) according to the temperature ratio RT = TL/TH of fully accelerated fragments. In such codes RT is given as input, either as an unique value for all fragmentations or as a function of AH; This temperature ratio RT being obtained by fitting the experimental ν(A) data with the respective prompt emission model code. This paper proposes a method for obtaining “experimental RT(AH)” (also based on experimental ν(A)), but without resorting to prompt emission model calculations for the fit of ν(A) data. So that this is an independent method providing RT(AH) which can be employed by any prompt emission model code in which the TXE partition is done at the full acceleration according to RT given as input. A procedure which facilitates the parameterization of RT(AH) is proposed, too. A prediction of the RT(AH) shape at very high excitation energies of the fissioning nucleus is also reported. The comparison of RT(AH) ratios obtained from any TXE partition based on modeling at scission with those provided by the present method can constitute a supplementary validation of the respective modeling at scission.
