1999Xu05 (also 2005Xu04): 139Dy produced and identified in 106Cd(36Ar,X) reaction at E=176 MeV. Measured p-γ1(x ray)-γ2(x ray)-t; He-jet; totally depleted silicon surface barrier detectors, HPGe detectors.
2000So11: 90Zr(197Au,X) E=30 MeV/nucleon; measured fragments charge and mass distribution and isotopic production σ=70 μb for the production of 139Dy
Q-value: Estimated uncertainties (2012Wa38): ΔS(n)=640, ΔS(p)=590, ΔQ(α)=640
Q-value: Q(εp)=10730 540, S(2p)=1010 590 (both from syst, 2012Wa38). S(2n)=24280 (theory, 1997Mo25)
