Pulsed-neutron decay measurements on BeO systems in the vicinity of the continuum bound

Abstract

Decay constants have been measured in BeO systems in the buckling range 0·0167–0·0342 cm⁻². The corresponding decay constants range from below the constant collision frequency limit, λ*, to values above the elastic continuum bound, λ_el. A range of λ_el(B²) has been determined experimentally and the results are compared with calculated values based on cross-section data generated by the GASKET code.
