A dynamical model based on effective Lagrangians is proposed to describe the bremsstrahlung reaction πN → πNγ at low energies. The ∆(1232) degrees of freedom are incorporated in a way consistent with both, electromagnetic gauge invariance and invariance under contact transformations. The model also includes the initial and final state rescattering of hadrons via a T-matrix with off-shell effect...

Nuclear shell model calculations predict the existence of super-heavy elements (SHE) that are tentatively synthesized through heavy-ion collisions. A complete description of the reaction to synthesize super-heavy elements is necessary to bridge these predictions with the experimental results on the fission time and residue cross sections. In this contribution, we will present the constraints th...

The extended boundary condition method (EBCM), or T-matrix method, has been applied to the determination of scattering cross sections of coated spheroidal particles in random orientation.We report the e!ects of varying size and core/shell ratio for a number of axial ratios. Di!erent scattering properties of equal-volume prolate and oblate spheroids, as well as the e!ect of nonsphericity on thin...

Differential cross sections of the γd → dπ 0 reaction were measured at photon beam energies between 0.5 and 2.0 GeV over a wide angular range in the CM system. The experiment was performed in Hall B at Jefferson Lab using the CLAS detector. The excitation function, especially at backward CM scattering angles, has been studied with regard to effects due to intermediate on-shell η and ω rescatter...
