Transfer Reactions As a Tool in Nuclear Astrophysics

چکیده

Nuclear reaction rates are one of the most important ingredients in describing how stars evolve. The study nuclear reactions involved different astrophysical sites is thus mandatory to address questions astrophysics. Direct measurements cross-sections at stellar energies very challenging - if all possible. This essentially due low interest (especially when it involves charged particles), and/or radioactive nature many key nuclei. In order overcome these difficulties, various indirect methods such as transfer method above or near Coulomb barrier used measure spectroscopic properties compound nucleus that needed calculate interest. this review, basic features and theoretical concept behind first discussed, then illustrated with recent performed experimental studies

Transfer reactions as tool for nuclear astrophysics : the 13 C ( α , n ) 16 O case

The cross section of the nuclear reactions involved in stellar nucleosynthesis (e.g. AGB stars) are often very difficult to measure directly at stellar energies because of their very small value. Moreover, this situation can be complicated by the existence of very low energy resonances and/or subthreshold resonances. Indirect methods such as transfer reactions and the ANC method offer the possi...

Electromagnetic Dissociation as a Tool for Nuclear Structure and Astrophysics

Coulomb dissociation is an especially simple and important reaction mechanism. Since the perturbation due to the electric field of the nucleus is exactly known, firm conclusions can be drawn from such measurements. Electromagnetic matrix elements and astrophysical S-factors for radiative capture processes can be extracted from experiments. We describe the basic theory, new results concerning hi...

Dense Plasmas, Nuclear Reactions and Astrophysics

A certain number of questions are raised to physicists and astrophysicists concerning : (1) the conditions under which stellar matter becomes a highly correlated plasma ; (2) the role of mass loss in the formation of dense matter ; (3) the evolution of white dwarfs accreting matter (with its consequences for the formation of compact X ray sources and pulsars) . 1 . Introduction.The solution of ...

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...
