203Tl(p,2n)202mPb


Bibliography of experimental data
This reaction is a major contribution to the nuclidic impurities in the production of 201Pb---201Tl.

A total of 4 cross section data sets were found in the literature in the energy range considered. The 4 publications were selected for further evaluation. Data measured on natural targets were transformed to represent the 203Tl(p,2n)202mPb reaction only up to 27 MeV (below threshold of 205Tl (p,4n) reaction). Only data sets that where already selected for the 203Tl(p,3n)201Pb reaction where considered.

The list of related references given below is accompanied with additional information. We mention availability of data in the computerized database EXFOR (if available, unique EXFOR reference number is given). Further, we indicate a reason why a data set was excluded (reference denoted by an asterisk *).

The data from papers where experimental numerical values were available (4 papers), are collected in Fig. 5.1.15a. All the 4 works were selected for further evaluation.

No calculations were performed as the codes only give access to total cross sections and not to separate isomers.
 Cross sections were calculated by Padé fit with 20 parameters. The results are compared to selected experimental data in Fig. 5.1.15b. The best approximation was judged to be the Padé 1 fit. Recommended cross sections are compared with selected experimental data, including their error bars, in Fig. 5.1.15c. Yields calculated from the recommended cross sections are presented in Fig. 5.1.15d. The corresponding numerical values for recommended cross sections and yields are tabulated in Tab. 5.1.15a and Tab. 5.1.15b, respectively.
