Neutron-proton pair transfer reactions and corresponding Weisskopf-type units

نویسندگان

چکیده

We introduce the concept of neutron-proton two-particle units ($np$-Weisskopf units) to be used in analysis ($^3$He,$p)$ and $(p,^3$He) \added{reactions on nuclei} along N=Z line. These are presented for conditions relevant $(n,j,\ell$) orbits expected from $^{16}$O $^{100}$Sn. As is case Weisskopf electromagnetic transitions, $np$-WU's will provide a simple, yet robust, measure isoscalar isovector $np$ pairing collective effects.

A unified diabatic description for electron transfer reactions, isomerization reactions, proton transfer reactions, and aromaticity.

While diabatic approaches are ubiquitous for the understanding of electron-transfer reactions and have been mooted as being of general relevance, alternate applications have not been able to unify the same wide range of observed spectroscopic and kinetic properties. The cause of this is identified as the fundamentally different orbital configurations involved: charge-transfer phenomena involve ...

Neutron Transfer to the Continuum Reactions

In this contribution we show that the theory of neutron transfer to the continuum reactions is an useful tool to study different characteristics of the single particle structure of nuclei. In one example we discuss properties of the single particle resonances in Pb. Another interesting application deals with the neutron breakup from weakly bound nuclei. Here one can use the theoretical calculat...

Photon Absorption on a Neutron - Proton pair in

We have developed a phenomenological quasi-deuteron model to describe photodisintegration reactions of He and He at intermediate photon energies, and compared the results with experimental data obtained by TAGX group in which contributions from photon absorption by pn pair were selectively observed. The data can be reproduced reasonably well, however there still remain certain discrepancies bet...
