Using density functional theory (DFT) with gradient-corrected exchange-correlation
functionals (B3LYP), we systematically study the electronic structure and bonding of oxygen …

Using first principles quantum mechanics (nonlocal density functional theory), we studied
the bonding and electronic states for clusters of Pt atoms. These calculations suggest the …

The isotropic Compton profile of mercury has been measured, using 661.65 keV gamma-
rays from a 20 Ci 137Cs source. To extract the true experimental Compton line shape …

We have measured the directional Compton profiles of a single crystal of hexagonal zinc
along the [00· 1],[10· 0],[11· 0] and [11· 1] directions using high-energy (662 keV) gamma …

The directional electron momentum density distributions (Compton profiles) of single‐crystal
cadmium have been measured in transmission and reflection experimental geometries …

We report the first-ever experimental Compton profiles (CPs) of CdTe measured along [100]
and [111] directions using 100mCi 241Am Compton spectrometer. The experimental …

Directional Compton profiles of single crystals of bismuth, Bi [100], Bi [110] and Bi [111] have
been measured with high accuracy for the first time using 662 keV γ‐radiation from a 137Cs …

In this paper, we present the first experimental Compton profile of ytterbium. Measurement
has been made, at an intermediate resolution (0.40 au), using gamma‐ray Compton …

We present the experimental Compton profile of polycrystalline terbium, using 661.65 keV
gamma-rays, emitted by 20 Ci137Cs. In the absence of band structure calculations …

This thesis is based on research done at the X-Ray Laboratory of the Department of Physics
(University of Helsinki, Finland), and at the beamline ID15B of the European Synchrotron …
