Interaction of slow neutrons with natural Rutenium, Rhodium, Cadmium and Thallium and some of their isotopes

By means of Christiansen filter technique the following bound coherent neutron scattering lengths were obtained:natRu:b=7.02 ± 0.02 fm108Cd:b=5.31 ± 0.24 fm103Rh:b=5.90 ± 0.04 fm110Cd:b=5.78 ± 0.08 fmnatTl:b=8.773 ± 0.015 fm111Cd:b=6.47 ± 0.08 fm203Tl:b=8.51 ± 0.08 fm112Cd:b=6.34 ± 0.06 fm205Tl:b=8.87 ± 0.07 fm114Cd:b=7.48 ± 0.05 fm116Cd:b=6.26 ± 0.09 fm In combination with some total cross section measurements with neutrons in the eV-energy range and with the compiled resonance parameters we deduced consistent sets of spin state scattering lengths and potential radii.
