what is the physical meaning of the scattering length of neutrons? What does mean -ve scattering length( for instance for 'H' !)??

Neutron scattering length is a measure of the average distance that a neutron travels through a material before it is scattered. It is a fundamental physical property that is used to study the structure and properties of materials at the atomic level.
Neutron scattering length is typically measured using neutron scattering experiments, where a beam of neutrons is directed at a material and the resulting pattern of scattered neutrons is analyzed. The distance between the neutron source and the detector is then used to calculate the scattering length.
Neutron scattering length is an important parameter in the field of materials science as it provides valuable information about the structure and properties of materials. It is also used in various research fields such as physics, chemistry, and biology to study the behavior of particles and atoms in different materials.
Neutron scattering length differs from other scattering lengths, such as X-ray or electron scattering lengths, because neutrons have no charge and interact differently with materials. This allows for unique insights into the atomic and magnetic structures of materials that may not be observable with other techniques.
Neutron scattering length is a fundamental property of neutrons and cannot be directly manipulated. However, it can be indirectly affected by changing the properties of the material being studied, such as its density or composition. Neutron scattering experiments can also be designed to specifically measure certain aspects of the scattering length, providing more detailed information about a material's structure and properties.
