.Ho-166-m is generated from the stable monoisotope 2268700100049
Ho-165 by irradiation in reactor. Four samples were 2268700100050
prepared. Thickness of each is 0.0125 mm, purity 2268700100051

1st irradiation of the foils was performed at the long2268700100053
irradiation plug of (KURRI) for 2 and 3 weeks. 2268700100054
The second irradiation of the target was performed in 2268700100055
a hydraulic transfer tube of Kyoto University reactor 2268700100056
for 10 hours with and without cadmium capsule. 2268700100057
