Empirical formula for neutron scattering lengths and cross sections

The neutrons are important tool to study the condensed matter and they can also be used in nuclear physics. Hence in the present work, we have formulated an empirical formula for neutron absorption cross sections, coherent and incoherent neutron scattering cross sections and coherent neutron and incoherent scattering lengths for different mass number nuclei of wide atomic number range 1
