A study of maximum pseudorapidity gap distributions in 16O-nucleus interactions at 3.7, 60 and 200A GeV/c

The main aim of this paper is to present some interesting results on event-by-event maximum 2-particle gap ([Formula: see text]) in the pseudorapidity space of the relativistic charged particles [Formula: see text] produced in the [Formula: see text]O-AgBr interactions at 3.7, 60 and 200[Formula: see text]A GeV/c. The distribution of [Formula: see text] has been obtained for the experimental and AMPT simulated data. Distinct peaks are obtained in the [Formula: see text]-distributions of the relativistic charged particles in low [Formula: see text]-region. Further, the position of the peak is found to depend on the incident energy. The experimental results are not well supported by the results obtained for the AMPT simulated data. The findings presented here may be found useful in understanding the mechanism of the multiparticle production in relativistic nuclear interactions.

Recent Progress in Gamow Shell Model Calculations of Drip Line Nuclei

The Gamow shell model (GSM) is a powerful method for the description of the exotic properties of drip line nuclei. Internucleon correlations are included via a configuration interaction framework. Continuum coupling is directly included at basis level by using the Berggren basis, in which, bound, resonance, and continuum single-particle states are treated on an equal footing in the complex momentum plane. Two different types of Gamow shell models have been developed: its first embodiment is that of the GSM defined with phenomenological nuclear interactions, whereas the GSM using realistic nuclear interactions, called the realistic Gamow shell model, was introduced later. The present review focuses on the recent applications of the GSM to drip line nuclei.
