We channeled 405 MeV/nucleon uranium ions in Si single crystals to determine the electron impact ionization cross sections for hydrogenlike‐berylliumlike uranium ions by 222 keV electrons. Our cross sections are 3.9, 11.0, 16.0, and 31.0 barns (+10

Energy spectra of inelastic scattered π+ mesons from 16O, 40Ca, 60Ni, and 208Pb at Tπ = 50 MeV have been obtained at θlab = 40° and 80° for nuclear excitation energies up to ≈ 25 MeV. Differential cross section for the observed low-lying state

Angular distributions for the reaction π + + d → p + p at 40, 50, and 60 MeV are compared with calculations employing a π N t matrix both on and off-shell and two different models for the deuteron. Within this framework, the data require a 4% D-s

The elastic scattering of 141.9 MeV 16 O from targets of 28 Si, 59 Co and 60 Ni has been studied using the oxygen beam from the Oak Ridge Isochronous Cyclotron (ORIC). Elastic angular distributions were measured in angular steps of about 0.7° (c.m.)

Differential cross sections for elastic scattering of $sup 12$C ions of 96 MeV, $sup 16$O ions of 129.5 and 192 MeV, and $sup 20$Ne ions of 161.2 MeV from $sup 208$Pb were measured and analyzed using the optical model. Values of the real potential ne

A neutron source designed for fusion-related radiation damage studies has been built based on the d + Be reaction. Using a 40 MeV, 20 μA deuteron beam from the Oak Ridge Isochronous Cyclotron neutron fluxes of (1–2) × 10 12 n/cm 2 ·s are obtaine

The response of plastic scintillator has been measured for monoenergetic proton beams of 70, 80, 90 and 100 MeV. Results are presented for the tail-to-peak ratio as a function of the cutoff energy below the peak.

X rays induced by 20‐MeV oxygen ions have been used to search for trace quantities of lanthanum on the surface of a NaCl crystal. The results demonstrate the sensitivity of the method to small quantities of heavy elements present on low‐Z matrice
