An iterative method for artefact reduction in X-ray computed tomography is applied to neutron tomography data of a massive copper cylinder with a central conical bore. The acquired neutron radiography projections are heavily influenced by a scattering contribution originating from the sample, thereby violating the exponential law of narrow beam attenuation. Because this leads to similar effects like beam hardening in X-ray computed tomography, we tested the performance of this iterative method mitigating artefacts in neutron tomography caused by a different physical process.

Davidson's method is widely used for finding the lowest eigenvalues of large matrices. Recently, mathematicians have shown that Davidson's derivation could be improved. They have corrected the derivation yielding a new iteration method. In this article this new method is adapted for realistic MRCI a
