Kinetic secondary electron emission from a solid target resulting from incidence of keV electrons or keV and MeV ions is treated theoretically on the basis of ionization cascade theory. The energy and angular distribution and the yield of secondary electrons are calculated for a random target. These quantities are det…

Solubilities of MgO in aqueous HC1 solutions at 23°±3°C were measured and combined with analyses of neat magnesium oxychloride cements, cured in sealed containers, to construct an equilibrium phase diagram for the system MgO‐MgCl 2 ‐H 2 O. Specific gravities and acidities of solutions saturated with MgO and relative h…
Raman scattering and infrared reflectance have been measured in 2H-MoSe 2 . We observed all Raman-active modes, A 1g , E 1g , E 2g 1 and E 2g 2 , and two infrared-active modes, E 1u 2 and A 2u 2 . Intralayer force constants are estimated from the central force model. The bond between metal (Mo) and chalcogen (Se) pred…
High‐temperature creep experiments were made on olivine single crystals under compressional stress to large strains. At strains larger than about 40 to 60%, dynamic recrystllization occurs and cellular wall dislocation structure is formed. Recrystallized grain size dg(µm) and cell wall spacing ds(µm) are dependent upo…

Absorption, luminescence, and excitation luminescence studies of dye molecules adsorbed onto ultrathin, variable-thickness silver films show strong coupling of the particle plasma resonances to the molecules. Luminescence from the dye is increased by excitation transfer from the silver particles for certain film thick…
The domain structures in BaTiO3 ceramics differ from those of single crystals. The spatial configuration of the domains in the ceramics has been derived from etch patterns. All observed etch patterns can be described by two types of domain configurations. Thin layered domains separated by 90 ° walls are piled up to fo…

ABSTRACT Differential Scanning Calorimetry (DSC) was used to study gelatinization phenomena of corn, potato, acid‐modified corn and smooth pea, and various legume starches. Two endothermic transitions were observed for starches heated in the presence of limited amounts of water (starch/water = 46–48% w/w). The effect…
Inelastic neutron scattering measurements on a single crystal of NaNO 3 have yielded the temperature behaviour of the lattice vibrations propagating along the threefold axis. Frequency, shifts and anomalous linewidths are observed near the order-disorder transition temperature (T c =276C). In general, the observed beh…
