Inclusive particle production in the geometrical two-chain model of soft hadronic interactions.
The geometrical two-chain model was established to describe the soft, low-energy hadronic interaction. The main aim of the model was the applicability of creating a fast and accurate Monte Carlo interaction generator of such processes in complex and time-consuming simulation calculations as, e.g., that of the simulations of the hadron passage through the thick media. In this paper we present the model predictions concerning the inclusive particle production characteristics. A comparison with the fritiof model frequently used for high-energy event generation and experimental results is given.
Inelasticity and intranuclear cascading in geometrical multichain model
The inelasticity in nucleus-nucleus collisions at high energies is calculated in the framework of geometrical multichain model. The very fast increase of the inelasticity is found as a result of a second-stage cascading process. The same behaviour is expected for all the models using the wounded nucleon idea. The simple formula for the number of wounded nucleons inside colliding nuclei does not need to be exact.
Gamma decay of the 9.042- and 9.805-MeV states in $sup 23$Na
$sup 12$C($sup 12$C,p$gamma$)$sup 23$Na proton-$gamma$ angular correlations were measured at E/subB/=38.82 MeV for the 9.042- and 9.805-MeV states in $sup 23$Na which decay to levels at 7.270, 6.235, and 5.534 MeV with branching ratios of 20%, 60%, and 20%, respectively, for the 9.042-MeV state, and 30%, 50%, and 20%, respectively, for the 9.805-MeV state. Angular correlations and lifetime data eliminate 17/2 assignments for either state.
