Equiangular lines, mutually unbiased bases, and spin models
We use difference sets to construct interesting sets of lines in complex space. Using (v, k, 1)-difference sets, we obtain k2−k+1 equiangular lines in Ck when k − 1 is a prime power. Using semiregular relative difference sets with parameters (k, n, k, λ) we construct sets of n + 1 mutually unbiased bases in Ck. We show how to construct these difference sets from commutative semifields and that ...
متن کاملinvestigation of high-spin rotational states in the atomic nucleus.
the ground state rotational bands of some rare earth nuclei show a rather strange behaviour at large values of angular momenta. the nuclear moment of inertia teta increases smoothly with angular momentum i up to i=12. then at about i=14 there is a sudden increase in the moment of inertia. the plot of teta versus the square of the angular velocity w gives a s-shaped curve. we attempt here to rep...

متن کاملCollisional depolarization and transfer rates of spectral lines by atomic hydrogen . IV : application to ionised atoms
The semi-classical theory of collisional depolarization of spectral lines of neutral atoms by atomic hydrogen (Derouich et al. 2003a; Derouich et al. 2003b; Derouich et al. 2004 and references therein) is extended to spectral lines of singly ionised atoms. In this paper we apply our general method to the particular cases of the 3d D and 4p P states of the CaII ion and to the 5p P state of the S...
متن کاملMecanismos de alargamento de linhas espectrais atômicas Line broadening mechanisms of atomic spectral lines
Os espectros de energia de átomos idealizados (isolados, parados e em temperatura 0K) são constitúıdos por um conjunto de linhas muito estreitas. Contudo, no mundo real, verifica-se que cada uma destas linhas são alargadas pela ação de vários tipos de influências externas. Uma discussão simplificada é apresentada sobre seus mecanismos e como cada um deles atua isoladamente sobre as linhas espec...
