Abstract

Coherent neutron scattering lengths and total cross sections have been measured on samples of ordinary Tb, Ho and Er and on isotopically enriched Er-compounds. From the experiment the following data were obtained:

  • - the coherent scattering lengths (in fm) of the bound atoms 159Tb(7.34 ± 0.02), 165Ho(8.44 ± 0.03), ordEr(7.79 ± 0.02), 162Er(9.01 ± 0.11), 164Er(7.95 ± 0.14), 166Er(10.51 ± 0.19), 167Er(3.06 ± 0.05), 168Er(7.43 ± 0.08), and 170Er(9.61 ± 0.06)

  • - the thermal absorption cross sections (in b) 141Pr(12.7 ± 0.6), ordNd(58 ± 1), 159Tb(30 ± 2), 165Ho (65 ± 2), ordEr (145 ± 2), 166Er (18 ± 2), 167Er(568 ± 9), 168Er(2.3 ± 0.3), and 170Er(15 ± 1). In combination with the resonance parameters, the measured coherent scattering lengths allowed the determination of potential scattering radii R′ which are of particular interest for the optical model theory.
