The interaction of 800-MeV ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ ions with a thin foil produces protons, the ground state and excited states of neutral ${\mathrm{H}}^{0}$ atoms, and unstripped ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ ions. We inve

The relative photodetachment cross section for decay into the H({ital N}=2) channel by the {sup 1}{ital P}{degree} shape resonance in H{sup {minus}} was measured, as well as that for decay into all channels. The branching ratio {sigma}({ital N}=2)/{s

Two resonances in the photodetachment spectrum of ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$, one just below the n=3 threshold and the other just below the n=4 threshold, were observed decaying into ${\mathrm{H}}^{0}$(n'=2)+e. The n=3 resonance shows a

The lifetime of 800-MeV ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$ ions against electron detachment in a static electric field was measured over a range of eight orders of magnitude in experiments at the High Resolution Atomic Beam Facility of the Los

We propose the use of photodetachment of H− by a focused, diffraction‐limited laser beam for measuring the profile and transverse emittance of an H− ion beam.

Non‐invasive laser diagnostics are capable of measuring p absolutely and δp/p of high‐energy H− ion beams. A Q‐switched Nd:YAG laser, operating at 0.266 μm, can excite narrow auto‐ionizing resonances in the H− ion. The measured width of

Using crossed laser-relativistic ion beam (800 MeV) techniques, we have measured two- and three-photon detachments of the 0.75 eV bound electron in H_ as a function of CO2 laser photon energy, intensity, and polarization. The threshold region for pho
