The incoherent scattering length of deuterium is much smaller ( 2.05 ( 3 ) barn ) making structural investigations significantly easier.
12.
There is a large difference in scattering length between protium (-0.374 ) and deuterium ( 0.667 ).
13.
Shot noise has been demonstrated in mesoscopic resistors when the size of the resistive element becomes shorter than the electron-phonon scattering length.
14.
The total cross-section for hydrogen is over 10 times that of deuterium, mostly due to the large incoherent scattering length of hydrogen.
15.
Their instrumentation now had better control so they used naturally " attracting " atoms of rubidium-85 ( having negative atom atom scattering length ).
16.
Even though rubidium-85 is more abundant, rubidium-87 has a positive scattering length, which means it is mutually repulsive, at low temperatures.
17.
Hence, the amplitude of scattering that characterizes the interaction of a neutron with a given isotope is termed the scattering length, " b ".
18.
In experimental settings, the Feshbach resonances provide a way to vary interaction strength between atoms in the cloud by changing scattering length, a sc, of elastic collisions.
19.
Neutron reflectometry measures the neutron " scattering length density " ( SLD ) and can be used to accurately calculate material density if the atomic composition is known.
20.
In this range, the sample must not be described at an atomistic level; one rather uses a continuum description in terms of an electron density or a neutron scattering length density.
