From bound states to resonances: analytic continuation of the wave function
G. Cattapan, E. Maglione
Single-particle resonance parameters and wave functions in spherical and deformed nuclei are determined through analytic continuation in the potential strength. In this method, the…
Spin observables for the pd <-> pi+ t process around the Delta resonance
L. Canton, G. Cattapan, G. Pisent +2
The proton analyzing power Ay0 and the deuteron tensor analyzing power T20 are evaluated for the pd <-> pi+ t process, in the energy region around and above the Delta resonance. Th…
The piNNN--NNN problem. Connectedness, transition amplitudes and quasi-particle approximation
Giorgio Cattapan, Luciano Canton
In this paper we review the present status of the piNNN--NNN problem. In particular, we re-consider the chain-labelled approach recently proposed by us, and identify a class of gra…
N-Body Theory Revisited and its Extension to the pinnn-NNN Problem^*
G. Cattapan, L. Canton
In order to approach the pion--multinucleon problem, we have found it convenient to reformulate the general N--body theory starting from the fully unclusterized (i.e., N <- N) ampl…
