specialization completed in U.S.S.R., Italy and Germany and a lifework dedicated
to the cyclotron from Ma ˘gurele Platform, initiated and then coordinated by him. He
was visiting professor at the Hahn-Meitner Institute in Berlin (in 1975 and 1976).
He elaborated the method of the pulse fascicule at the cyclotron which was
undertaken afterwards at TANDEM accelerator; he established a cryogenics laboratory, a Laboratory of Hyperfine Interactions recognized worldwide as prestigious
in the field. He conducted research collaboration projects with institutes and
universities in Erlangen, Konstanz, Lyon and Orle ´ans and among the applicative
researches conducted at the cyclotron we are mentioning the studies of the solids
and the iradiation with rapid neutrons in biological purposes. During more than
40 years of scientific research he discovered over 100 new nuclear izomers, with
lifespans of micro- and mili- seconds; he conducted measurements of nuclear
magnetic moments and nuclear and quadrupolar electrical moments, permitting to
obtain informations regarding the nuclear structure, especially for the nucleons with
valence around the magical numbers. Using the pulse fascicule technique he
perfected nuclear methods to study the dynamics of the punctual form irradiation
imperfections in metals; he also studied the gradients of the electrical fields in
binary metalic materials, using nuclear probes in excited nuclear states. He elaborated many techniques with several applications tribology, medicine, biology and
environment and published important studies: O metoda ˘ simpla ˘ de obt ¸inere a
impusului zero la Ciclotron (1962); Short-Lived Isomers Observed in AlphaParticle Bombardaments of Natural Elements (1966); Nuclear isomers with halflives in the 30–3000 μs range, excited in 24 MeV alpha-particle bombardment on
natural targets (1967); Lifetime and g-Factor of the 181 keV Level in
78 Br (1971);
Quadrupole Moments of High Spin Isomeric States in Sn Isotopes (1976); Radiation

GEAVIT MUSA (1931, Palazu Mare, Constant ¸a County – 2010, Bucharest) was
a physicist, Correspondent Member of the Romanian Academy since 2009. (Rusu
2016, 178–9) He established new laboratories of research at “Ovidius” University
and he sustained a top scientific activity in plasma physics and its applications in
technical domanins, in the conversion of the thermic energy in electrical energy
(he obtained a higher efficiency generator), in physical processes of ultra high
vacuum (Coms ¸a-Musa vacuum pomp) and in the study of the optical properties
of an extended range of systems (the opto-galvanic effect). He studied monocolor
plasma displays and established a pilot line for their production at Cinescope
Industries, Bucharest and his research led to the discovery of the thermal ionic
arch in vacuum, obtaining plasma with special properties allowing for the formation
of thin adherent, low rugosity and compact nanostructured layers. He emphasized
the “M effect”, consisting in the reduction of the emission specter to only one line
and his research resulted in new approved products: stabilovolt tubes, tritium
selfluminescent tubes, stroboscopic tubes with special characteristics, signaling
