The magnetic hyperfine fields at Br and Kr nuclei in nickel have been measured by heavy ion implantation techniques. Extrapolating to 0 K, H = −0.7(1) T is obtained for Kr and H = +8.0(1) T for Br, in qualitative agreement with theoretical values.

A pronounced difference in magnetic behavior at distinct lattice sites has been found for recoil-implanted 54 Fe ions in fcc cerium metal using the perturbed-angular-distribution method. Of the implanted ions 25(5)% show predominantly spin magnetism

Measurements of the temperature dependence of the chemical shift at Fe nuclei in ${\mathrm{FeS}}_{2}$ (pyrite) and Fe impurities in ${\mathrm{RuS}}_{2}$ (laurite) were performed on high-purity synthetic single-crystal samples using the perturbed-angu

The g-factor of the t1/2=9.3 ns, Iπ=5/2 + state at Ex=130 keV in77Br has been measured by observation of the time differential perturbed angular correlation (PAC) in a Co single crystal. The experimental value g=1.32(1) gives evidence for large defo

High Rydberg states in neon ions are formed in interactions of 85-MeV $^{20}\mathrm{Ne}^{6+}$ ions with a thin carbon-foil target and with a helium-gas target. The effect of a weak, transverse, static electric field on the Rydberg states is investiga

Two-electron capture involving simultaneous transfer of an electron to the continuum (or to a Rydberg state) and a bound state has been investigated for collisions of 3.5 MeV/u Ne/sup 10+/ with He, Ne, and Ar targets. The extent of this double captur
