Proportionality Relations in Charge-Exchange Reactions

Excitation of Giant Resonances in Pion Charge-exchange Reactions

Nuclear halo structure from quasielastic charge-exchange reactions

Neutron and proton densities in the nuclear periphery are investigated within (p,n) charge-exchange isobar transitions. For this purpose we have developed parameterfree optical potentials 1) with a detailed treatment of the in-medium tτ part of the effective interaction. Non local coupled-channel Lane equations are solved to obtain the scattering observables. The use of conventional proton and ...

Single Pion Production in Neutrino Reactions and Estimates for Charge - Exchange Effects

We calculate single pion production by neutrinos in the resonance region. We consider both charged and neutral current reactions on free protons and neutrons. We present differential and total cross sections which can be compared with experiments. Then we use these results to calculate the spectra of the emerging pions including the Pauli suppression factor and rescattering corrections for reac...

Symmetries and exchange relations

The first chapter of Marx’s Capital is concerned with an anlysis of the commodity. It is a somewhat difficult chapter to read, but it is considered by many scholars to be essential to understanding his whole conceptualisation of capitalism. It is a relatively formal text but not in the sense that we would now describe a scientific or mathematical text as being formal. Instead of mathematics or ...

Prospects for ultracold carbon via charge exchange reactions and laser cooled carbides.

Strategies to produce an ultracold sample of carbon atoms are explored and assessed with the help of quantum chemistry. After a brief discussion of the experimental difficulties using conventional methods, two strategies are investigated. The first attempts to exploit charge exchange reactions between ultracold metal atoms and sympathetically cooled C(+) ions. Ab initio calculations including e...
