Excited states in the well-deformed rare earth isotopes Sm and Er were populated via “safe” Coulomb excitation at the Munich MLL Tandem accelerator. Conversion electrons were registered in a cooled Si(Li) detector in conjunction with a magnetic transport and filter system, the Mini-Orange spectrometer. For the first excited 0 state in Sm at 1099 keV a large value of the monopole strength for th...

In this work, a novel method for determining the principal directions (maxima) of the diffusion orientation distribution function (ODF) is proposed. We represent the ODF as a symmetric high-order Cartesian tensor restricted to the unit sphere and show that the extrema of the ODF are solutions to a system of polynomial equations whose coefficients are polynomial functions of the tensor elements....

A quantum phase transition is usually achieved by tuning physical parameters in a Hamiltonian at zero temperature. Here, we show that the ground state of a topological phase itself encodes critical properties of its transition to a trivial phase. To extract this information, we introduce an extensive partition of the system into two subsystems both of which extend throughout the bulk in all dir...

Constrained Relativistic Mean Field (RMF) calculations have been carried out to estimate excitation energies relative to the ground state for superdeformed bands in the mass regions A ∼ 190 and A ∼ 150. It is shown that RMF theory is able to successfully reproduce the recently measured superdeformed minima in Hg and Pb nuclei. Superdeformation has become the recent years one of the most interes...

absence of enough connection between forum and action is principal reason for existence of exorbitant jurisdiction. some jurisdictional rules such as conclusion place of contract in the historical ground especially revolution of communication instrument has lost its logical ground. because of political interest such as protection of forum nationals, spite of states increasing cooperation has be...
