The Long Duration Exposure Facility (LDEF) was host to several individual experiments designed to characterize aspects of the meteoroid and space debris environment in low Earth orbit. It was realized from the very start, however, that the most complete way to accomplish this goal was to exploit the meteoroid and debris record of the entire LDEF. The Meteoroid and Debris Special Investigation Group (M&D SIG) was organized to achieve this ...
A conformal mapping of the scattering cosine of an elastic scattering process is used to remove a divergence caused by crossed channel singu larities. A numerical application to pi n - pi n forward dispersion relations is considered. (Author)
