In a more general four-boson case, the correlation between tetramer and trimer binding energies has a non-fixed slope, which expresses the dependence on the new scale. The associated scaling function generates a family of Tjon lines. This conclusion relies on a recent study with weakly-bound four identical bosons, within a renormalized zero-range Faddeev-Yakubovsky formalism. © 2012 Springer-Verlag.213-216engArtigo10.1007/s00601-012-0356-8WOS:000314063300035Acesso restrito2-s2.0-8487305940337406397265453158621258845956348
