Notes: Supersymmetric three-dimensional Schrödinger equations describing central problems do not lead, in general, to supersymmetric one-dimensional radial equations. Such a context is discussed, in connection with the two main supersymmetrization procedures (with or without spin-orbit coupling terms). The inverse problem is also considered, starting from a supersymmetric radial equation. © 1995 American Institute of Physics.

Notes: Abstract Near second and third contact during a solar eclipse the spatial spectrum of the solar illumination changes as the relative power at high spatial frequencies increases strongly. Since groundlevel atmospheric scintillation depends on a weighted integral of the image power spectrum, we can expect to see a measureable time dependence to solar scintillation during an eclipse. This effect was observed during an annular solar eclipse and quantitatively compared with a scintillation model.
