Elastic Scattering of Alpha-Particles by Heavy Elements

Elastic Scattering of Yuimwa Particles

Elastic scattering -of the heavy particle obeying Bose statistics is examined by the relativistically invariant equations recently developed by Proca and by Dirac. Perturbation calculus of the "variation of constants" type is applied. For the evaluation of certain sums occurring in the scattering cross sections, destruction operators are constructed similar to those first developed by Weisskopf...

Decoherence of quantum kinematical correlations: Elastic scattering of identical particles

Determination of Alpha Particles and Heavy Metals Contamination in Meat Samples in Najaf, Iraq

Introduction: The aim of the present study was to determine the levels of alpha particles and heavy metals contamination in the meat products consumed in Najaf, Iraq. Moreover, this study was also targeted toward comparing the results with those in the literature and making appropriate conclusion and recommendations. Material and Methods: This study determined the track of alpha particles and ...

Large-angle oscillations in heavy ion elastic and inelastic scattering

The oscillatory behaviour observed at large angles in heavy ion elastic and inelastic scattering cross-sections at energies above the Coulomb barrier, is interpreted as an interference effect between rainbow scattering and the contribution coming from the negative branch of the classical deflection function. In heavy ion reactions, at energies near and above the Coulomb barrier, the structure o...

Elastic electron scattering by C2F4.

Recent measurements [R. Panajotovic, M. Jelisavcic, R. Kajita, T. Tanaka, M. Kitajima, H. Cho, H. Tanaka, and S. J. Buckman, J. Chem. Phys. 121, 4559 (2004)] and calculations [C. Trevisan, A. E. Orel, and T. N. Rescigno, Phys. Rev. A 70, 012704 (2004)] of the elastic electron cross section for C(2)F(4) differ materially from our earlier calculations [C. Winstead and V. McKoy, J. Chem. Phys. 116...
