Abstract:With a view towards implementation in microscopic transport simulations of heavyion collisions, the properties of spin-isospin modes are studied in nuclear matter consisting of nucleons and ∆ isobars that interact by the exchange of π and ρ mesons. For a standard p-wave interaction and an effective g ′ short-range interaction, the dispersion relations for the spin-isospin modes, and the associated amplitudes, are calculated at various nuclear densities and temperatures, within the random-phase approximation. Quantities of physical interest are then extracted, including the total and partial ∆ decay widths and the ∆ cross sections in the nuclear medium. The self-consistent inclusion of the ∆ width has a strong effect on the ∆ cross sections at twice normal nuclear density, as compared with the result of ignoring the width. Generally, the obtained quantities exhibit a strong density dependence, but are fairly insensitive to the temperature, at least up to T = 25 MeV. Finally, it is described how these in-medium effects may be consistently included into microscopic transport simulations of nuclear collisions, and the improvements over previous approaches are discussed.

A b s t r a c t . Angular and momentum distributions as well as grain densities of charged secondaries emitted in inelastic proton-nucleon interactions are measured. The cross-section of the A (1 236) isobar production in the events of the type p p + p n n f is calculated. The theoretical predictions of both the isobar and the O.P.E. model are compared with the experimental data. The transverse momentum distribution of both pions and protons is presented and explained by various theoretical models.

Die theoretisrheii Vorhersagen der beiden Isobar-und 0. P. E. Modelle wurden mit den experimentellen Daten verglichen. Die Verteilnng der Transversal-Impulse der Pionen und Protonen wird angegeben und durch verschiedene theorehehe Modelle erklart.
