Reaction mechanism in odd-even staggering of reaction cross sections

Odd-Even Staggering of Nuclear Masses: Pairing

The odd-even staggering of nuclear masses was recognized in the early days of nuclear physics. Recently, a similar e ect was discovered in other nite fermion systems, such as ultrasmall metallic grains and metal clusters. It is believed that the staggering in nuclei and grains is primarily due to pairing correlations (superconductivity), while in clusters it is caused by the Jahn-Teller e ect. ...

Revisiting the Even-odd Staggering in Fission-fragment Yields

The even-odd staggering observed in the experimental fission-fragment nuclear-charge yields is investigated over a wide systematics of fission fragments measured at Lohengrin in direct kinematics and at GSI in inverse kinematics. The general increase of the even-odd staggering in the fission-fragment charge yields towards asymmetric charge splits is explained by the absorption of the unpaired n...

O + HCI Cross Sections and Reaction Probabilities in DSMC

A chemical reaction model, suitable for use in the Direct Simulation Monte Carlo (DSMC) method, is developed to simulate hypervelocity collisions of an important reaction in atmospheric-jet interactions O(3P)+HCl(1Σ ) OH(2Π)+Cl(2P). The model utilizes the Quasi-Classical Trajectory (QCT) method with two potential energy surfaces (PES), new benchmark triple A and A surfaces and London-Eyring-Pol...

Electromagnetic reaction cross sections in relativistic heavy ion collisions

The goal of this project was to produce a computer program to predict the cross section of relativistic heavy ion collisions between given projectile and target nuclei . An explanation of the usefulness ofrelativistic heavy ion collision analysis is presented. The use of the WeiszackerWilliams method of virtual quanta for enhancing reaction cross sections of this type is discussed. Quantum-mech...
