Kinetic model of metallofullerene formation in contact arc generator
(Fullerene Science and Technology, 1999)
A kinetic model of the metallofullerene growth process in a contact are generator is developed. The metals chosen for the kinetic analysis were lanthan and calcium. An optimum starting composition of composite electrode ...
Radiopharmaceutical complexes of technetium and tin: Physicochemical and biochemical research
(Journal of Radioanalytical and Nuclear Chemistry, 1999)
The list of the developed Tc-99m-kits in our research center is given, while the whole research work as a basis of Tc-99m scanning agents production is described. Research involved physico-chemical studies of both types ...
Magnetic moments of transition metals overlayers on fcc Ni surface
(Journal of Physics: Condensed Matter, 1998)
We calculate the magnetization profile in the (111) surface of face-centred cubic (fcc) Ni covered by a monolayer or a bilayer of 3d and 4d transition metals. The observed trends can be explained as in earlier works in ...
Dielectric investigation of magnesium salt of 12-tungstophosphoric acid hydrate
(Solid State Ionics, 1999)
Magnesium salt of 12-tungstophosphoric acid (WPA) hydrate MgHPW12O40-14H(2)O has been investigated in the microwave (X-band) and in the lower frequency (5 Hz-500 kHz) region. The specimens were obtained by pressing powder. ...
Detuned primary RF coupling system for variable frequency cyclotrons
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1998)
A new concept of impedance matching for an RF amplifier coupled to a cyclotron cavity, named detuned primary coupling, is proposed. It does not require the motion of the coupling loop in vacuum and the matching for different ...
Application of a precise fiber-optical dee position measurement system in the cyclotron RF system design
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1999)
A new fiber-optical dee position measurement system is developed for the VINCY cyclotron. The system includes a sensor head, a coherent optical fiber bundle and a light detector with control electronics. The sensor head ...
