  2. Sr-88 Koehler (2000) 5320 points up to 350 keV isolated points in the Koehler’s region Hughes (1950) 1 point at 1 MeV (2.1 mb) Pd-102 no usable data point Xe-124 no usable data point Te-130 many points up to 10 keV about 40 points 10 keV to 20 MeV (60 mb to 0.6 mb) about 25 points 10 keV to 6 MeV (shifted by 3 orders - error) Sm-152 two sets (plus isolated points) 3 keV to 3 MeV (1.5 b to 50 mb) one set (4 points) 25 keV to 1 MeV (shifted by 3 orders) Ho-165 several sets of data up to 20 MeV (10 b to 0.7 mb) one set (5 points) 20 keV to 1 MeV (shifted by 3 orders) Ir-191 several sets up to 20 (25) MeV (EXFOR v. 1.62 – June 2004) RCM "ND ...

  14. Data of Bensch et al. (4 points) by error in EXFOR shifted by 3 orders RCM "ND ... Therap. Radiois.", IAEA Nov. 2004

  17. The resulting excitation functions of all 7 targets [only 5 shown here, where the experimental data are presented in the 2002 version of EXFOR – the two remaining reactions (on Pd-102 and Xe-124) have been also calculated and the excitation functions have been proposed, but not demonstrated as a plot today] have been prepared as ENDF files ready to be given to the IAEA NDS.
