Each target was a F145600100012 thin 151Eu layer with a thickness of ~100 mu-g/cm2 F145600100013 and a spot diameter of 22 mm, electrochemically F145600100014 deposited on the surface of a titanium foil with a F145600100015 thickness of 2 mu-m. Eu2O3 with enrichment of 97.5 + F145600100016 -0.1%, with impurity content of 0.02% Nd, 0.02% Gd, F145600100017 <0.01% Sm provided by the state reserve of stable F145600100018 isotopes was used for electrode-position. F145600100019 DETECTOR (HPGE) Ultrapure germanium detector with an energy F145600100020 resolution of 850 eV for the 122 keV line and 1.8 keV F145600100021 for the 1.33 MeV line was used for gamma F145600100022 spectrometry. The distance from the source to the F145600100023 detector was 6 or 11 cm, depending on the radiation F145600100024 intensity, and was chosen so that the dead time did F145600100025 not exceed 10-15%. F145600100026 METHOD (STTA,GSPEC) F145600100027 (EDEG) Aluminum foils with a thickness of 9 to 100 mu-mF145600100028 were placed between the targets, serving as beam F145600100029 monitors or degraders. F145600100030 (ACTIV) The irradiation time was about 30 min, the F145600100031 average beam current was ~ 1.7 mu-A. Measurements of F145600100032 radioactivity were started 4 h after EOB in the first F145600100033 experiment (60 MeV) and after 24 h in the second (43 F145600100034 MeV), and were repeated several times during the F145600100035 week to determine the activity of radionuclides with F145600100036 different half-lives. Typical acquisition time was F145600100037 400-1800 s. F145600100038 MONITOR (13-AL-27(A,X)11-NA-24,,SIG) F145600100039 (22-TI-0(A,X)24-CR-51,,SIG) F145600100040 ERR-ANALYS The uncertainty in measuring the beam energy was F145600100041 estimated as + -1 MeV. The uncertainty of the F145600100042 thickness of the absorbers and monitor was determined F145600100043 by multiple weighing and was estimated as 0.1-1 mu-m, F145600100044 depending on the foil mass. The calculated total F145600100045 energy uncertainty was 1-1.7 MeV, depending on the F145600100046 position of the target in the stack. F145600100047 (ERR-T) The uncertainty was calculated as the square F145600100048 root of the sum of the squares of the individual F145600100049 uncertainties: F145600100050 (ERR-1) uncertainty for the detector efficiency; F145600100051 (ERR-3) uncertainty for the target thickness; F145600100052 (ERR-4) uncertainty for nuclear data; F145600100053 (ERR-5) uncertainty for the current value.
