We have made improved measurements of the neutron capture and total cross sections for {sup 137}Ba over a sufficiently wide range of energies so that the reaction rate at s-process temperatures (kT=6{endash}23 keV) can be determined solely from the d

The ORELA experiment on the neutron charge radius has been reevaluated. The neutron transmission of liquid thorogenic ${}^{208}\mathrm{Pb}$ with the neutron time-of-flight method in the neutron energy range from 0.08 to 800 eV was measured. Additiona

Transmutation of actinide waste into fission products could be enhanced by using resonance fission of odd-odd target materials; those of interest are 232Pa, 238Np, and 242Am. Fission cross-section measurements of two of these short-lived materials we
