    "abstract": "The conditions for occurrence of the Efimov effect is briefly described using\nhyperspherical coordinates. The strength of the effective hyperradial\n$\\rho^{-2}$ potential appearing for two or three large scattering lengths is\ncomputed and discussed as function of two independent mass ratios of the three\nconstituent particles. The effect is by far most pronounced for asymmetric\nsystems with three very different masses. One Efimov state may by chance appear\nin nuclei. Many states could be present for systems with one electron and two\nneutral atoms or molecules. Estimates of the number of states and their sizes\nand energies are given.",
