The isotopic composition: Mo-92 D402100100013 (0.87%),Mo-94 (93.9%), Mo-95 (2.85%), Mo-96 (1.04%), D402100100014 Mo-97 (0.40%), Mo-98 (0.75%), Mo-100 (0.22%) Chemical D402100100015 purity > 99.1% D402100100016 3 to 6 mg/cm**2 Mo metal and 5 to 10 mg/cm**2 MoO3 D402100100017 layer were sedimented on 25 microns of Cu backings D402100100018 then covered by 10 microns of Al foil. For yield D402100100019 measurement 33-162 mg/cm**2 thick Mo-94 targets were D402100100020 used. D402100100021 METHOD (STTA,ACTIV,EXTB)the primary incident proton energy D402100100022 was 19.2 Mev determined from the ratio of monitor D402100100023 reactions of Cu-63(p,2n)Zn-62 and Cu-63(p,n)Zn-63 D402100100024 induced on the first monitor foil according to H.Piel D402100100025 et Al., Radiochim acta,57,1,1992. Several stacks D402100100026 containing 6-8 samples were irradiated for 15 min at D402100100027 100 namp beam current, bellow 8 MeV extra irradiation D402100100028 was made on 3 samples for 60 min at 200 namp. For D402100100029 measuring the thick target yield and isotopic D402100100030 impurities 1 hr irradiaton with 45 - 200 namp were D402100100031 made.
