Femto-neutrons or 'femtons' are fast neutrons of femtometer wavelength, a million times shorter than the current nanotechnology diagnostic probes which operate on nanometer scale.
In the nuclear case, the structures are based on nucleons such as protons and neutrons and those building blocks are measured using femtometers (10-15).
While in the neutron stars, these structures are based on protons and neutrons, which exist in the scale of femtometers, the structures found in cells can be measured in the scale of nanometers - a difference of a factor of a million.
Since scattering lengths are of the order of a few femtometers, the second term in the bracket is of the order of [10.
