PRODUCTION OF NEUTRON-RICH Ca ISOTOPES IN TRANSFER-TYPE REACTIONS

Abrasion-Ablation Model for Neutron Production in Heavy Ion Reactions

In heavy ion reactions, neutron production at forward angles is observed to occur with a Gaussian shape that is centered near the beam energy and extends to energies well above that of the beam. This paper presents an abrasion-ablation model for making quantitative predictions of the neutron spectrum. To describe neutrons produced from the abrasion step of the reaction where the projectile and ...

Neutron reactions in astrophysics

The quest for the origin of matter in the Universe had been the subject of philosophical and theological debates over the history of mankind, but quantitative answers could be found only by the scientific achievements of the last century. A first important step on this way was the development of spectral analysis by Kirchhoff and Bunsen in the middle of the 19th century, which provided first in...

Parity Violation in Neutron Capture Reactions

In the last decade, the scattering of polarized neutrons on compound nucleus resonances proved to be a powerful experimental technique for probing nuclear parity violation. Longitudinal analyzing powers in neutron transmission measurements on p-wave resonances in nuclei such as La and Th were found to be as large as 10%. Here we examine the possibilities of carrying out a parallel program to me...

Cross-sections for production of neutron deficient Sg - isotopes in reactions

Due to low cross-sections for the production of heaviest nuclei the choice of the optimum reaction for specific nuclides is crucial for nuclear structure investigations based on α-γ-decay spectroscopy, which demand maximum numbers of observed events. Following previous decay studies of No [1] and Rf [2] an experiment to investigate Sg, the next heavier N=153 isotone, for which only rough decay ...
