“…Therefore, the van der Waals interaction is almost negligible, and the dipole-dipole interaction governs the dynamics. Table II also presents homonuclear pairs of atoms, bosonic or fermionic, with a large total angular momentum J and therefore a large permanent magnetic moment: pairs of the transition metal atom Cr, with atomic ground level 3d 5 4s 7 S 3 [43,44], pairs of the lanthanide atoms Dy [45,46] and Er [47,48], with respective atomic ground levels 4f 10 6s 2 5 I 8 and 4f 12 6s 2 6 H 6 . In their lowest state 2S+1 L J |M J |=J, with Landé factor g J , these atoms possess a large permanent magnetic dipole moment m=µ B g J J, and two collision partners strongly interact via magnetic dipole-dipole interaction.…”
