natKr(p,x)81Rb


Bibliography of experimental data

 

 

 

Five publications with experimental cross-section data were identified in the literature for incident particle energies up to 120 MeV and are represented with uncertainties in Fig. All data. The article by Steyn et al. (1991) contained two data sets represented as (a) and (b) in the figure. The article by Kovacs et al. (1991) contained two data sets, respectively measured on natural Kr targets and on enriched 82Kr targets represented as (nat) and (enr) in the figure. The data measured on enriched targets from Lamb et al. (1978) and Kovacs et al. (1991)(enr) were normalised and included in the evaluation up to 20 MeV. The data of 3 sets were rejected and not considered for further analysis. The remaining four datasets of Refs. were considered as input for a least-squares Pade fit. The Pade functions with 14 parameters were fitted to 78 selected data points with a χ2=0.99 covering the energy range up to 120 MeV as shown in Fig. Recommended. The uncertainties (including a 4% systematic uncertainty) are 100% near the reaction threshold, but decrease steadily to below 10% from 20 MeV on.
