We investigate ultracold collisions in a novel mixture of $^6$Li and $^{53}$Cr fermionic atoms, discovering more than 50 interspecies Feshbach resonances via loss spectroscopy. Building a full coupled-channel model, we unambiguously characterize the

Protonium annihilation densities in a unitary coupled channel model

Autor: E. Ydrefors, Jaume Carbonell

Publikováno v: Eur.Phys.J.A
Eur.Phys.J.A, 2021, 57 (11), pp.303. ⟨10.1140/epja/s10050-021-00609-2⟩

We consider a unitary coupled channel model to describe the low energy proton-antiproton scattering and the lower Coulomb-like protonium states. The existence of deeper quasi-bound states of nuclear nature is found to be a consequence of the experime

New results in low-energy fusion of 40Ca+90, 92Zr

Autor: Stefanini, A.M., Montagnoli, G., Esbensen, H., Čolović, Petra, Corradi, L., Fioretto, E., Galtarossa, F., Goasduff, A., Grebosz, J., Haas, F., Mazzocco, M., Soić, Neven, Strano, E., Szilner, Suzana

Background: Near- and sub-barrier fusion of various Ca + Zr isotopic combinations have been widely investigated. A recent analysis of 40Ca+96Zr data has highlighted the importance of couplings to multiphonon excitations and to both neutron and proton

The recently developed four-body continuum-discretized coupled-channels (CDCC) method, making use of the binning procedure [1], is applied to the reaction 6He+64Zn at 13.6 MeV (around the Coulomb barrier). Excellent agreement with available elastic d
