Efimov effect in nuclear three-body resonance decays.
We investigate the effects of the nearly fulfilled Efimov conditions on the properties of three-body resonances. Using the hyper-spheric adiabatic expansion method we compute energy distributions of fragments in a three-body decay of a nuclear resonance. As a realistic example we investigate the 1- state in the halo nucleus 11Li within a three-body model 9Li + n +n model. Characteristic feature...
متن کاملEfimov states with strong three-body losses
Introduction. – Motivated by nuclear physics, Efimov discovered that three particles with short-ranged two-body interactions of scattering length |a| = ∞ can support an infinite series of weakly bound trimer states [1]. In contrast to systems of nucleons or of He atoms, ultracold gases of alkali metal atoms offer the possibility to tune a by using a Feshbach resonance, and thus to go more deepl...
متن کاملEfimov Effect and Higher Bound States in a Three Particle System
We study the J=O bound states for a system of, three identical spinless particles interacting in pairs through delta-shell potentials. The Efimov states are identified, and their wavefunctions obtained. We have found a new family of bound states, which occur for higher values of the attractive coupling strength. *Supported in part by the U. S. Energy Research and Development Administration. TSu...
متن کاملZero Range Scattering Theory Ii . Minimal Relativistic Three - Particle Equations and the Efimov Effect
We present numerical results obtained from a minimal relativistic model for three distinguishable particles of equal mass driven by a single bound or virtual state for each pair, which is a relativistic generalization of the zero range non-relativistic two particle scattering length model. In contrast to the non-relativistic case, the relativistic kinematics makes the three body equations conve...
