Description

The various attempts made to separate the spurious energy dependence of the empirical optical potential from the dynamical one by using a dispersion relation for the theoretical optical potential are reviewed in the light of a recent calculation of the mass operator in the Brueckner-Hartree-Fock approximation. The non-relativistic and relativistic treatments are compared and their implications are pointed out. A comparison between the calculations based on the dispersion relation and those based on the nucleon-nucleon scattering amplitude is also made. (orig.)

Abstract (German)

Die verschiedenen Versuche, die unechte Energieabhaengigkeit des empirischen optischen Potentials von der dynamischen Energieabhaengigkeit mit Hilfe einer Dispersionsrelation fuer das theoretische optische Potential zu trennen, werden aufgezeigt und im Hinblick auf neuere Rechnungen des Massenoperators in der Naeherung von Brueckner-Hartree-Fock diskutiert. Die nichtrelativistische und relativistische Behandlung wird verglichen und ihre Folgerungen dargestellt. Ausserdem werden Rechnungen auf der Basis von Dispersionsrelationen und Rechnungen, die von der Nukleon-Nukleon Streuamplitude ausgehen, miteinander verglichen. (orig.)
