Activation cross sections / Ge detector / Neutron-induced reactions / γ -ray spectroscopy / Tin region / Neutron generatorSummary. We measured activation cross sections via γ -ray spectroscopy using high-purity germanium detectors for 16 reactions induced by (14.4 ± 0.2) MeV neutrons on isotopes of tin. The cross sections are: σ( 112 Sn(n, 2n) 111 Sn) = (1104 ± 43) mb, σ( 112 Sn(n, p) 112m In) = (33.6 ± 2.1) mb, σ( 112 Sn(n, p) 112g In) = (42.7 ± 3.1) mb, σ( 114 Sn(n, 2n) 113 Sn) = (1270 ± 115) mb, σ( 114 Sn(n, p) 114m2 In) = (20.5 ± 1.1) mb, σ( 115 Sn(n, p) 115m In) = (35.2 ± 2.6) mb, σ( 116 Sn(n, p) 116m2 In) = (11.1 ± 0.5) mb, σ( 117 Sn(n, n p) 116m2 In) = (1.35 ± 0.11) mb, σ( 117 Sn(n, p) 117m In) = (4.5 ± 0.4) mb, σ( 117 Sn(n, p) 117g In) = (12.8 ± 0.7) mb, σ( 117 Sn(n, n ) 117m Sn) = (246 ± 21) mb, σ( 118 Sn(n, 2n) 117m Sn) = (816 ± 70) mb, σ( 118 Sn(n, α) 115g Cd) = (1.26 ± 0.16) mb, σ( 120 Sn(n, α) 117m Cd) = (0.27 ± 0.04) mb, σ( 120 Sn(n, α) 117g Cd) = (0.29 ± 0.06) mb and σ( 124 Sn(n, 2n) 123m Sn) = (590 ± 26) mb.Two 112 Sn targets enriched to 62.5% and 84%, respectively, were used for these measurements in addition to the natural tin. The cross sections were compared with experimental data found in the literature, with published empirical formulae and with model calculations including also the pre-equilibrium contribution. For reactions which do not involve protons from below the closed Z = 50 shell, the agreement to the data is reasonable, it is somewhat weaker for the (n, p) reactions and still worse in the case of (n, α), where, however, the pre-equilibrium component is not described properly by the models included so far. The possibility of production of 111 Sn → 111 In generator system is considered.
