20. New results on light hypernuclei

M. Jean-Marc Richard (IPNL)

16/10/2014 09:00

We revisit the spectroscopy and some production mechanisms of light hypernuclei with single or double strangeness. There is already an abundant literature on the subject [1-4], and we generally recover the published results. We first review the rigorous limits on the possibilities of “Borromean” binding, i.e., bound states whose subsytems and unbound, and discuss whether novel possibilities...

44. Structure of neutron-rich hypernuclei

Dr Emiko Hiyama (RIKEN)

Recently, we have new data on neutron-rich hypernulei, such as nn$\Lambda$ and $^7_{\Lambda}$He($^6$He+$\Lambda$). Especially, in $^7_{\Lambda}$He, it is planned to search experiment of new excited states at JLab, which is expected to be resonant state. Then, it is requested to study these hyper nuclei to treat bound state as well as resonant states. Here, I will report the level structure of...

19. At the threshold of the Efimov effect

M. Yvan Castin (CNRS)

The three-body Efimov effect leads, for a binary interaction of infinite s-wave scattering length and no dimer state, to an infinite number of trimer states, which is quite remarkable for a short-range interaction. Of particular conceptual interest would thus be a system where a control parameter alpha allows to continuously switch on and off the Efimov effect. When alpha crosses the critical...

40. The rare gas clusters

Dr Elena Kolganova (BLTP JINR)

16/10/2014 11:40

This work is devoted to the theoretical study of the properties of rare gas clusters. Spectra and wave functions are calculated for dimers of the atoms He, Ne, Ar, Kr, Xe and Rn. Calculations were performed for all possible homogeneous and heterogeneous pairs of rare gas atoms. The Tang - Toennies, Aziz and Lennard - Jones potential models are used for description the interatomic...
