abstract = {In this study we focussed on the question of how to grow
crystals as large as possible in light of their use as
samples for neutron protein crystallography. We investigated
the early stages of the crystallisation process where the
directions are set between the growth of many small crystals
or few large ones. We used lysozyme since it is considered
as a model system for crystal growth. Small angle neutron
scattering was used in combination with static light
scattering in order to realize an extended q-range. In situ
dynamic light scattering at the neutron scattering sample
cell was used to obtain an overview of all sizes present in
the crystallisation process. We could observe a fractal
growth of the crystal seeds with a change in the fractal
dimension from 1.0 to 1.7 in the first 90 min. This can be
interpreted that at first a branched crystal seed is formed
which grows more in a linearly. Later, the space between the
arms is filled to cross over to a more densely packed
fractal.},
