The disks obtained were packed in thin 3153200100010 Al-capsules to ensure mechanical stability. Aluminium 3153200100011 and iron monitor foils (Al 1.00 mm and Fe 0.50 mm 3153200100012 thick) of the same size as a sample were attached in 3153200100013 front and at the back of each capsule. 3153200100014 FACILITY (CYCLO,2GERJUL) Variable energy compact cyclotron CV28 3153200100015 irradiations with quasi-monoenerg.neutrons in the 3153200100016 energy range of 7.8 to 13.3 MeV 3153200100017 (CCW,3HUNKOS) D-T neutron generator in the 3153200100018 13.8-14.7 MeV energy range 3153200100019 INC-SOURCE (D-D) 2GERJUL.
