Bibliography of experimental data
Five publications containing cross-section data relevant for the 70Ge(α,2n)72Se reaction were found: Amiel (1959) (70Ge target), Calboreanu et al. (1987) (70Ge target), Mushtaq and Qaim (1990) (natGe target, original data normalized for 70Ge abundance, only values below 27 MeV published), Levkovskij (1991) (70Ge target), Takács et al. (2016) (natGe target, normalized, only data points below 37 MeV considered). All available cross-section values for the 70Ge(α,2n)72Se reaction up to 48 MeV and their uncertainties are shown in Fig. All data. The Pade functions with 7 parameters were fitted to 77 selected data points with a χ2 = 1.35 and covering the energy range up to 48 MeV as shown in Fig. Recommended. The uncertainties (including 4% systematic uncertainty) start at 100% up to 18 MeV, decrease to below 7% from 22 to 48 MeV on, increase to reach 31% at the highest energy.
