“…For example, McGlNNIS [2] gave the ratio a value 22/78, while BAEDECKER et al [10] and TANG et al [12] took it as 42.9/57.1 and 47.1/52.9, respectively, although these groups did depend totally on the result of McGlNNIS's beta-ray measurement [2],…”

High purity of a 117 In m and ' 17 In 6 isomer mixture was achieved by a two-step preparation, in which a 98.85% enriched 116 Cd target was irradiated with either thermal neutrons or 12 MeV deuterone and the Cd-fraction was purified in the first step, and then the 117 In-activities accompanying by the beta-decay of 117 Cd were collected. The chemical effect accompanying the internal conversion electron emission at the isomeric transition of 117 In m was utilized in order to separate 117 In g from the interfering isomer 1 ' 7 In m . All the 117 In-activities were complexed with EDTA, and 117 In 8 liberated from the complex at the IC decay of 1 " In m was extracted by an oxine-chloroform solution to obtain a 117 In g sample isolated from the isomer 117 In m . The half-lives of a 117 In isomer-pair were determined to be 116.1 + 0.2 min and 43.1 ± 0.2 min for the m-and g-states, respectively.

“…So far, numerous experiments [1][2][3][4][5][6][7][8][9][10][11][12][13] have been devoted to the investigation of the decay character of the isomer pair of 117 In (the half-lives are roughly 120 and 40 min for the metastable-and ground-states, respectively).…”
