Uniqueness of ab initio shape determination in small-angle scattering

open access: yes, 2003
Scattering patterns from geometrical bodies with different shapes and anisometry (solid and hollow spheres, cylinders, prisms) are computed and the shapes are reconstructed ab initio using envelope function and bead modelling methods.

Scattering into cones I: Potential scattering [PDF]

open access: yesCommunications in Mathematical Physics, 1969
In the non-relativistic time-dependent theory of scattering, we compute the probability that a particle with given initial state should scatter into a cone with apex at the origin. A formula for this probability is found which holds good for a large class of short-range potentials and also for Coulomb potentials. The formula is obtained by showing that
