O067700100040 METHOD (STTA) Each stack contained 3-6 sandwiches samples O067700100041 and several Cu and Ti foils as energy degrader and O067700100042 monitor foils. 12 stacks were irradiated. O067700100043 (ACTIV) The stacks were irradiated at a beam O067700100044 current of about 100 nanoamperes. While investigating O067700100045 the 122-Te(P,N)122-I reaction, which leads to the O067700100046 short-lived product 122-I, the irradiation time was 5 O067700100047 minutes, in other cases it was 20 minutes.
