The production of high specific activities of tin, <SUP>113</SUP>Sn and <SUP>117m</SUP>Sn, with a cyclotron had been studied. Thick target yields for the reactions (A) <SUP>113</SUP>In(d,2n)<SUP>113</SUP>Sn, (B) <SUP>115</SUP>In(α,pn)-<SUP>117m</SUP>Sn and (C) <SUP>110</SUP>Cd(α,n)<SUP>113</SUP>Sn+<SUP>111</SUP>Cd(α,2n)-<SUP>113</SUP>Sn+ <SUP>114</SUP>Cd(α,n)<SUP>117m</SUP>Sn were determined for several incident particle energies. The reactions A and B are available for the production of the single tin activity. Reaction C is preferable to the others in the total yields of tin activities for the energy range studied, i. e., up to the energy of about 5 MeV. per nucleon of the incident particle. A thick target yield for reaction B has also been obtained from the excitation function up to the alpha particle energy of 40 MeV. The procedures for the carrier-free isolation of the tin activity from indium and cadmium targets by coprecipitation and ion exchange have also been described.
