A novel, spectrally tunable light-source utilizing light emitting diodes (LED's) for radiometric, photometric, and colorimetric applications is described. The
An algorithm is presented for assembling tiles into a variable spaced grating, the one-dimensional analogue of Fresnel zone plate. The algorithm supports
Two colliding atoms can absorb a photon and be photoassociated into an excited, diatomic molecule, NIST researchers investigated the fundamental rate at which
In this paper the classical Rayleigh-Sommerfeld and Kirchhoff boundary-value diffraction integrals are solved in closed form for circular apertures and slits
Electron-impact excitation cross sections are calculated and presented for the dipole-and spin-allowed transitions from the ground states to the np 2P states
