Collisional processes of [Formula: see text] with a silicon surface were investigated. Size-selected [Formula: see text](n=0–30) were allowed to collide with a silicon surface at collision energies per [Formula: see text] of 1–150 eV at almost normal incidence angles. All the anions scattered from the surface were I −, I −( CO 2), I −( CO 2)2, [Formula: see text], [Formula: see text], and [Formula: see text]. The molecular dynamics simulation revealed that the dissociation of [Formula: see text] occurs through vibrational and rotational excitation. The [Formula: see text] dissociation was found to be either retarded or accelerated by the presence of the solvent CO 2 molecules. The solvation effects on the dissociation of [Formula: see text] were explained in terms of energy transfer between [Formula: see text] and CO 2 solvent molecules and a complex formed on the surface at the moment of the collision.

In the 30 years since the discovery of the nucleosome, our picture of it has come into sharp focus. The recent high-resolution structures have provided a wealth of insight into the function of the nucleosome, but they are inherently static. Our current knowledge of how nucleosomes can be reconfigured dynamically is at a much earlier stage. Here, recent advances in the understanding of chromatin structure and dynamics are highlighted. The ways in which different modes of nucleosome reconfiguration are likely to influence each other are discussed, and some of the factors likely to regulate the dynamic properties of nucleosomes are considered.
