scattering length उदाहरण वाक्य

The incoherent scattering length of deuterium is much smaller ( 2.05 ( 3 ) barn ) making structural investigations significantly easier.
There is a large difference in scattering length between protium (-0.374 ) and deuterium ( 0.667 ).
Shot noise has been demonstrated in mesoscopic resistors when the size of the resistive element becomes shorter than the electron-phonon scattering length.
The total cross-section for hydrogen is over 10 times that of deuterium, mostly due to the large incoherent scattering length of hydrogen.
Their instrumentation now had better control so they used naturally " attracting " atoms of rubidium-85 ( having negative atom atom scattering length ).

Even though rubidium-85 is more abundant, rubidium-87 has a positive scattering length, which means it is mutually repulsive, at low temperatures.
Hence, the amplitude of scattering that characterizes the interaction of a neutron with a given isotope is termed the scattering length, " b ".
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.
Neutron reflectometry measures the neutron " scattering length density " ( SLD ) and can be used to accurately calculate material density if the atomic composition is known.
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.
