Band oscillator strengths for electronic transitions in CO were obtained at the Synchrotron Radiation Center of the University of Wisconsin-Madison. Our focus was on transitions that are observed in interstellar spectra with the Far Ultraviolet Spect

Direct implantation into interstitial sites has been found for Fe in Al at temperatures below 200 K. This result was obtained from an in-beam Mossbauer experiment, which assures that each Fe atom comes to rest in its own isolated defect cascade.

The nucleus 215Fr was studied using the 208Pb(11B,4n) and 204Hg(15N, 4n) reactions. The measurements included αγ, γγ, and ee coincidence experiments as well as γ-ray and α-particle DPAD studies. The decay scheme gives levels up to a 3068 keV 39

An in-beam Mossbauer spectrometer was set up at the VICKSI heavyion accelerator in Berlin. Coulomb excited Mossbauer nuclei can be implanted into arbitrary sample materials. Measuring temperatures may be varied from 5 K to 650 K. A typical scpectrum

The time differential perturbed angular distribution method (PAD) was used to measure theg-factor and the electric quadrupole interaction in a Cd single crystal for thet1/2=140 ns,Iπ=7/2+ isomer in125Xe. Theg-factor isg=+0.264(10) and the quadrupole
