title: Structural studies of adenovirus type 2 by neutron and X-ray scattering.
abstract: Small-angle neutron and X-ray scattering have been used to investigate various aspects of the structural organization of adenovirus type 2. Neutron scattering allows the determination of the radial distribution of DNA and protein, which because of the highly icosahedral form of the virus allows it to be described in terms of three icosahedral shells. X-ray scattering shows that the distance between the major coat proteins (hexons) in the capsid is 100 +/- A. Evidence was also observed for an organization in the nucleoprotein core that gives rise to a maximum in the X-ray scattering at 1/29 A-1.
