Each target was a F1456 1 12 thin 151Eu layer with a thickness of ~100 mu-g/cm2 F1456 1 13 and a spot diameter of 22 mm, electrochemically F1456 1 14 deposited on the surface of a titanium foil with a F1456 1 15 thickness of 2 mu-m. Eu2O3 with enrichment of 97.5 + F1456 1 16 -0.1%, with impurity content of 0.02% Nd, 0.02% Gd, F1456 1 17 <0.01% Sm provided by the state reserve of stable F1456 1 18 isotopes was used for electrode-position. F1456 1 19 DETECTOR (HPGE) Ultrapure germanium detector with an energy F1456 1 20 resolution of 850 eV for the 122 keV line and 1.8 keV F1456 1 21 for the 1.33 MeV line was used for gamma F1456 1 22 spectrometry. The distance from the source to the F1456 1 23 detector was 6 or 11 cm, depending on the radiation F1456 1 24 intensity, and was chosen so that the dead time did F1456 1 25 not exceed 10-15%. F1456 1 26 METHOD (STTA,GSPEC) F1456 1 27 (EDEG) Aluminum foils with a thickness of 9 to 100 mu-mF1456 1 28 were placed between the targets, serving as beam F1456 1 29 monitors or degraders. F1456 1 30 (ACTIV) The irradiation time was about 30 min, the F1456 1 31 average beam current was ~ 1.7 mu-A. Measurements of F1456 1 32 radioactivity were started 4 h after EOB in the first F1456 1 33 experiment (60 MeV) and after 24 h in the second (43 F1456 1 34 MeV), and were repeated several times during the F1456 1 35 week to determine the activity of radionuclides with F1456 1 36 different half-lives. Typical acquisition time was F1456 1 37 400-1800 s. F1456 1 38 MONITOR (13-AL-27(A,X)11-NA-24,,SIG) F1456 1 39 (22-TI-0(A,X)24-CR-51,,SIG) F1456 1 40 ERR-ANALYS The uncertainty in measuring the beam energy was F1456 1 41 estimated as + -1 MeV. The uncertainty of the F1456 1 42 thickness of the absorbers and monitor was determined F1456 1 43 by multiple weighing and was estimated as 0.1-1 mu-m, F1456 1 44 depending on the foil mass. The calculated total F1456 1 45 energy uncertainty was 1-1.7 MeV, depending on the F1456 1 46 position of the target in the stack. F1456 1 47 (ERR-T) The uncertainty was calculated as the square F1456 1 48 root of the sum of the squares of the individual F1456 1 49 uncertainties: F1456 1 50 (ERR-1) uncertainty for the detector efficiency; F1456 1 51 (ERR-3) uncertainty for the target thickness; F1456 1 52 (ERR-4) uncertainty for nuclear data; F1456 1 53 (ERR-5) uncertainty for the current value.
