Nonequilibrium neutron scattering

Neutron scattering. In a series of experiments, Bou6 et al. have studied by neutron scattering the conformational relaxation of the labelled chain after the stepwise deformation. In the short time-scale, the observed relaxation is well described by the Rouse dynamics. In the long time-scale (near t/ ), no clear indication has been found so far for the contraction of the contour length. Various reasons for this behaviour are conceivable such as the limited range of the scattering wave vector or polydi rsity of the sample. On the other hand the results may indicate the importance of the tube deformation in the nonequilibrium state. ...
