The conversion of kinetic energy into target-like fragment excitation and orbital angular momentum into fragment spin has been studied in the reaction 333 MeV Si with ' 'Ta. The light charged particles were detected in a small, highly segmented, 4m phoswich detector system placed in the spin spectrometer, a 4m NaI array which served as a neutron and gamma detector. Multiplicities of light charg...
A complex problem is solved herej we show how to write Dyson's equations for trie (Ising) spin-glass that relate the propagator G ta trie mass operator M. In other words we are able to reduce trie inversion of an ultrametric matrix M to the solution of a Dyson's equation in ail sectors (for the replicon sectcr trie result had already been derived). It turns oui that what renders the problem tra...
A method to calculate numerically the multiplicity of a solution to a system of algebraic equations is presented. The method is an application of Zeuthen’s rule which gives the multiplicity of a solution as the multiplicity of a united point of an algebraic correspondence defined naturally by the system. The numerical calculation is applicable to a large scale system of algebraic equations whic...

Dimers are the smallest chemical objects that show magnetic anisotropy. We focus on 3d and 4d transition metal dimers that have magnetic ground states in most cases. Some of these magnetic dimers have a considerable barrier against re-orientation of their magnetization, the so-called magnetic anisotropy energy, MAE. The height of this barrier is important for technological applications, as it d...
This paper describes a very general approach to the calculation of the Zeeman splitting effect produced by an external magnetic field on the rotational levels of diatomic molecules. The method is valid for arbitrary values of the total electronic spin and of the magnetic field strength -that is, it holds for molecular electronic states of any multiplicity and for both the Zeeman and incomplete ...
This article reports on a search for dark matter pair production in association with bottom or top quarks in 20.3 fb−1 of pp collisions collected at √ s = 8 TeV by the ATLAS detector at the LHC. Events with large missing transverse momentum are selected when produced in association with high-momentum jets of which one or more are identified as jets containing b-quarks. Final states with top qua...
In the reactions between multiplet molecules, there is a strict rule of conservation of the total spin multiplicity between starting materials and products. In radical pair reactions, the combination of two doublet species forms one singlet and three triplet sublevels. Figure 1 shows a vector diagram of the spin states of a radical pair and their abbreviates in the presence of magnetic fields. ...
Using single- and multireference approaches we have examined many of the low-lying electronic states of oxo-Mn(salen), several of which have not been explored previously. Large complete-active-space self-consistent-field (CASSCF) computations have been performed in pursuit of an accurate ordering for the lowest several electronic states. Basis set and relativistic effects have also been conside...
In this paper we consider the dynamics of the real polynomials of degree d + 1 with a fixed point of multiplicity d ≥ 2. Such polynomials are conjugate to fa,d(x) = axd(x−1)+x, a ∈ R{0}, d ∈ N. Our aim is to study the dynamics fa,d in some special cases.
