Invariants and bonnet-type theorem for surfaces in $\r^4$
Georgi Ganchev, Velichka Milousheva
In the tangent plane at any point of a surface in the four-dimensional Euclidean space we consider an invariant linear map of Weingarten-type and find a geometrically determined mo…
Gamma Background Measurements at BEO Moussala
A. Mishev, E. Hristova
Recent measurements of radiation gamma background at high mountain altitude, namely at Basic Environmental Observatory Moussala (42°10' 45" N; 23° 35'07"E, 2925m a.s.l.) are carrie…
Scaling Function, Spectral Function and Nucleon Momentum Distribution in Nuclei
A. N. Antonov, M. V. Ivanov, J. A. Caballero +4
The link between the scaling function extracted from the analysis of (e,e') cross sections and the spectral function/momentum distribution in nuclei is revisited. Several descripti…
Bohr Hamiltonian with deformation-dependent mass term for the Davidson potential
Dennis Bonatsos, P. E. Georgoudis, D. Lenis +2
Analytical expressions for spectra and wave functions are derived for a Bohr Hamiltonian, describing the collective motion of deformed nuclei, in which the mass is allowed to depen…
Why the sunspot cycle is double peaked
Katya Georgieva
Many sunspot cycles are double peaked. In 1967 Gnevyshev suggested that actually all cycles have two peaks generated by different physical mechanisms, but sometimes the gap between…
Simultaneous Description of Even-Even, Odd-Mass and Odd-Odd Nuclear Spectra
H. G. Ganev, A. I. Georgieva
The orthosymplectic extension of the Interacting Vector Boson Model (IVBM) is used for the simultaneous description of the spectra of different families of neighboring heavy nuclei…
