Robin, good point The Efimov state is generally overlooked, as we have noted before. There is something special about 3 identical resonantly bound units (esp bosons) even if the state is transitory, especially where the vectors are orthogonal on a rotating plane. (see the animation on the Wiki entry).
Consider the Efimov state in the context of light lithium and the evidence of a substantial nuclear anomaly with lithium-6 due to transitory clustering of 3 deuterons, replacing the normal nucleus. The Italian researcher Claudio Spitaleri is a leading proponent. https://www.sciencedirect.com/science/article/pii/S037026931500653X Robin wrote: In reply to Jed Rothwell's message >J.
