    "abstract": "Very recently the atomic masses of neutron-rich Zr isotopes, from $^{96}$Zr\nto $^{104}$Zr, have been measured with high precision. Using a schematic\nInteracting Boson Model (IBM) Hamiltonian, the evolution from spherical to\ndeformed shapes along the chain of Zr isotopes, describing at the same time the\nexcitation energies as well as the two-neutron separation energies, can be\nrather well reproduced. The interplay between phase transitions and\nconfiguration mixing of intruder excitations in this mass region is succinctly\naddressed.",
