Practically the same scattering length
is obtained from the real k-dependence of the phase shift (see the lower left graph in Fig.
collided gold atoms to produce abundant antiprotons and measured two important parameters of their interaction: the scattering length
and the effective range.
b], the scattering length

The neutron-scattering experiments, in this situation, should be performed with protonated polymers where the contrast of some structural elements (defects) is determined by the coherent scattering length
density of material.
Bringing together writings by an international group of researchers working in different areas of quantum physics, the proceedings includes such topics as universality in few-body systems with large scattering length
, simulations of dilute Fermi gases, normal persistent currents and gross shell structure in high spin, geometric aspects of the shell model, and quantum phase transitions in two-fluid systems.
DenPro also displays the electron density or neutron scattering length
density obtained in a crystallography experiment.
By selectively deuterating either the chromophore or the polymer, a difference in the scattering length
densities of these two components is introduced without significantly affecting the electron density.

If I(Q) is an intensity of small-angle scattering and [Delta][rho] is a scattering length
density difference, then I(Q) is proportional to the square of [Delta][rho] :
Titanium has a negative scattering length
and UCN cannot be held in this trap when uncoated.
