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 density inside the micelles [[rho].

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] [15]:

Titanium has a negative

scattering length and UCN cannot be held in this trap when uncoated.
