Total cross sections for electron capture have been measured for ${\mathrm{O}}^{q+}(1\ensuremath{\le}q\ensuremath{\le}8)$, ${\mathrm{Fe}}^{q+}(4\ensuremath{\le}q\ensuremath{\le}15)$, ${\mathrm{Mo}}^{q+}(4\ensuremath{\le}q\ensuremath{\le}18)$, ${\math

An oscillatory dependence on ionic charge of total electron-capture cross sections has been observed for multiply charged heavy projectiles incident on an atomic hydrogen target. The oscillatory behavior is attributed to interference caused by the lo

The Holifield Heavy Ion Research Facility has been in routine operation since July 1982. Beams have been provided using both the tandem accelerator alone and a coupled mode in which the Oak Ridge Isochronous Cyclotron is used as an energy booster for

If we define a heavy-ion "space" bounded by the three axes of mass, energy, and intensity, it becomes clear that there are large parts of this space which are completely unexplored. This, by itself, is an attractive situation since unexpected phenome

Cross sections for single electron capture by ${\mathrm{Si}}^{q+}$ ($2\ensuremath{\le}q\ensuremath{\le}9$) incident on atomic and molecular hydrogen have been measured in the relative-collision-velocity range (3.1-6.3)\ifmmode\times\else\texttimes\fi

A hydrogen arc discharge has been run in the top five units (fifteen 20 cm tube sections) of the ORNL tandem accelerator to test the effectiveness of this method of cleaning the high voltage electrodes. The discharge was maintained in both the high-

The measurement of electron-transfer cross sections sigma in ion collisions with atomic hydrogen has been extended to iron ions with mass number A = 56, charges q between +4 and +13, and specific energies E/A between 27 and 290 keV/amu. The charge-st

The location of a second 2+ state is established for six -even-even nuclei by means of Coulomb excitation produced by 4 to 5 Mev protons. The relatively weak excitation of these states is detected by a measurement of the gammaray yields from singles
