Abstract
Abstract
Coherent neutron scattering lengths and total cross sections have been measured on samples of Co, Sn and on isotopically enriched Sn-oxides. The following data were obtained:
• the coherent scattering lengths (in fm) of the bound atoms 59Co (2.49 ± 0.02), natSn (6.22 ± 0.01) 116Sn (6.10 ± 0.01), 117Sn (6.59 ± 0.08), 118Sn (6.23 ± 0.04), 119Sn (6.28 ± 0.03), 120Sn (6.67 ± 0.04), 122Sn (5.93 ± 0.03), and 124Sn(6.15 ± 0.03);
• the thermal absorption cross sections (in b) natSn (0.569 ± 0.005), 116Sn (0.50 ± 0.03), 117Sn (0.77 ± 0.06), 118Sn (0.24 ± 0.06), 119Sn (2.19 ± 0.06), 120Sn (0.55 ± 0.06), 122Sn (0.19 ± 0.06), and 124Sn (0.43 ± 0.06).
New bound levels were evaluated for the investigated nuclei. In combination with the resonance parameters the measured scattering lengths allowed the determination of potential scattering radii R' which are of particular interest for the check of the optical model.
