The present invention relates to the determination of a spatial formation parameter such as slowing down length and porosity in a measurement while drilling ('MWD') tool. The invention, more particularly, relates to the use of a neutron source and multiple neutron detectors in an MWD tool to determine the slowing down length of neutrons in the formation and to derive the formation porosity from the determined slowing down length.
