Total Neutron Cross Section of OrientedHo165from 2 to 135 MeV

Abstract
The effect of nuclear orientation on the total neutron cross section of the highly deformed Ho165 nucleus has been measured from 2 to 135 MeV. The data are successfully fitted by adiabatic coupled-channel calculations. The origin of this effect can also be understood by a semiempirical model which makes use of both the black-nucleus model and the nuclear Ramsauer effect.
