This welcome address will briefly present the Ettora Ma jorana Centre for Scientific Culture of Erice, and stress the importance of quantum few-body systems at the edge of stability.

51. Few-body reactions in nuclear astrophysics

Prof. Eduardo Garrido (Instituto de Estructura de la Materia, CSIC, Madrid, Spain)

Talks at Critical Stability V (Erice, October 2008)

Stellar nucleosynthesis reactions are responsible for the abundances of the different elements in the Universe. These reactions happen at very low relative energies between the nuclei involved, and the calculation of the corresponding production rates is one of major issues in Nuclear Astrophysics. These reactions can be of different nature (radiative capture, rearrangement processes...)...

19. Few-Body Approaches and Problems in Hypernuclei

Prof. Avraham Gal (Racah Institute of Physics, Hebrew University, Jerusalem)

Talks at Critical Stability V (Erice, October 2008)

It takes two nucleons to bind a Lambda hyperon, and perhaps as many as three nucleons to bind two Lambda hyperons. In my talk I will review few-body calculations which are relevant for deciphering the onset of binding in Lambda hypernuclei and in Lambda-Lambda hypernuclei. I will also discuss the onset of binding for Xi hyperons, stabilizing them against the free-space conversion Xi + N...

37. The ab initio no-core shell model

Dr Christian Forssén (Chalmers University of Technology)

Talks at Critical Stability V (Erice, October 2008)

The ab initio no-core shell model (NCSM) is a well-established theoretical framework aimed at an exact description of nuclear structure starting from high precision interactions between the nucleons [1,2]. The principal foundation of the method is the use of effective interactions appropriate for the large, but finite, harmonic-oscillator model spaces employed in the calculations. These...

58. Consistent α-cluster description of the Hoyle state in 12 C

Prof. Oleg O. I. Kartavtsev (Dubna, Russia)

Talks at Critical Stability V (Erice, October 2008)

Normal

During the recent years, there is a continuous interest to the experimental and theoretical study of the 12 C nucleus [1, 2, 3, 4]. In this respect, of special importance is the description of the Hoyle state, which was predicted more then 50 years ago merely from the abundance of elements in the universe. Whereas the Hoyle state is fairly well studied experimentally, e. g., its...
