We present the results of a study of charged pion production in C + C collisions at incident beam energies of 1A GeV and 2A GeV using the HADES spectrometer at GSI. The main emphasis of the HADES program is on the dielectron signal from the early phase of the collision. Here, however, we discuss the data with respect to the emission of charged hadrons, specifically the production of π mesons, w...

Elastic and inelastic scattering of 'Li from "C have been measured at incident energies of 63 and 78.7 MeV. The experimental data were obtained over an angular range from 8„,=8' to 40'. Optical model parameters have been extracted by fitting the elastic scattering data, and deformation lengths have been obtained for the 'Li* (0.48 MeV) state and the "C~ (4.44 MeV) state. No single parameter set...

Recently, the fusion cross sections of the reactions 12C(12C,α)20Ne and 12C(12C,p)23Na have been measured by γ-ray spectroscopy at energies as low as 2.10 MeV in the center of mass [10]. These measurements employed targets of ultra-low hydrogen contamination to suppress background which had hindered previous studies of the reactions. In this report the results are discussed relative to several ...

The mol-ecular structure of the title compound, C18H21N3S, shows a twisted conformation with a dihedral angle of 67.45 (4)° between the aromatic ring planes and an N-C-C-S torsion angle of -5.01 (13)°. The imidazolidine ring and the aniline moiety make a dihedral angle of 56.03 (4)° and the asscociated C-N-C angle is 125.71 (10)°. The guanidine-like C=N double bond is clearly localized, with a ...

In this paper, we proposed a three-point iterative method for finding the simple roots of non- linear equations via mid-point and interpolation approach. The method requires one evaluation of the derivative and three(3) functions evaluation with efficiency index of 81/4 ≈ 1.682. Numerical results reported here, between the proposed method with some other existing methods shows that our method i...
