The residual nucleon-nucleon interaction is investigated by analyzing the electromagnetic transitions to some magnetic states of 48Ca in the RPA framework. In particular the strength of the tensor part of the interaction is studied by comparing the calculated results with the available experimental information. It is found that the tensor force, as given by the (π+ρ)-exchange model, must be reduced by a factor between 30 and 60%. This result, when compared with the ~60% reduction factor found for 208 Pb , shows a certain dependence on the nucleus.

Nucleon Nucleon Interaction

Since Yukawa proposed that the pion is responsible for mediating the nucleon-nucleon interaction, meson exchanges have been widely used in understanding hadron-hadron interactions. The most studied mesons are the σ, π, ρ, and ω, while other heavier mesons are often argued to be less relevant because they lead to short range interactions. However, whether the range of interactions is short or long should be judged with respect to the size of the system studied. We propose that one charmonium exchange is responsible for the formation of the ΩcccΩccc dibaryon, recently predicted by lattice QCD simulations. The same approach can be extended to the strangeness and bottom sectors, leading to the prediction on the existence of ΩΩ and ΩbbbΩbbb dibaryons, while the former is consistent with the existing lattice QCD results, the latter remains to checked. In addition, we show that the Coulomb interaction may break up the ΩcccΩccc pair but not the ΩbbbΩbbb and ΩΩ dibaryons.
