Intertwined quantum phase transitions in odd-mass Nb isotopes
A. Leviatan, N. Gavrielov, F. Iachello
A detailed analysis of odd-mass Nb isotopes, in the framework of the interacting boson-fermion model with configuration mixing, discloses the effects of an abrupt crossing of state…
Interplay between shape-phase transitions and shape coexistence in the Zr isotopes
N. Gavrielov, A. Leviatan, F. Iachello
We investigate the evolution of structure in the zirconium isotopes where one of the most complex situations encountered in nuclear physics occurs. We demonstrate the role of two c…
Intertwined Quantum Phase Transitions in the Zr Isotopes
N. Gavrielov, A. Leviatan, F. Iachello
We explore the situation of intertwined quantum phase transitions (IQPTs), for which a QPT involving a crossing of two configurations is accompanied by a shape evolution of each co…
Phase space factors and half-life predictions for Majoron emitting decay
J. Kotila, J. Barea, F. Iachello
A complete calculation of phase space factors (PSF) for Majoron emitting decay modes is presented. The calculation makes use of exact Dirac wave functions with finite nu…
Neutrinoless double electron capture
J. Kotila, J. Barea, F. Iachello
Direct determination of the neutrino mass is at the present time one of the most important aims of experimental and theoretical research in nuclear and particle physics. A possible…
Limits on the neutrino mass from neutrinoless double- decay
J. Barea, J. Kotila, F. Iachello
Neutrinoless double- decay is of fundamental importance for the determining neutrino mass. By combining a calculation of nuclear matrix elements within the framework of the micr…
Evidence for tetrahedral symmetry in 16O
R. Bijker, F. Iachello
We derive the rotation-vibration spectrum of a 4-alpha configuration with tetrahedral symmetry, T_d, and show evidence for the occurrence of this symmetry in the low-lying spectrum…

J. Kotila, F. Iachello
A complete and improved calculation of phase space factors (PSF) for and decay, as well as for the competing modes , , and , is pres…
Analytic descriptions for transitional nuclei near the critical point
M. A. Caprio, F. Iachello
Exact solutions of the Bohr Hamiltonian with a five-dimensional square well potential, in isolation or coupled to a fermion by the five-dimensional spin-orbit interaction, are cons…
Re-analysis of the nucleon space- and time-like electromagnetic form factors in a two-component model
R. Bijker, F. Iachello
Recent experimental data on space-like and time-like form factors of the nucleon are analyzed in terms of a two-component model with a quark-like intrinsic three-quark structure an…
Algebraic Models of Hadron Structure II. Strange Baryons
R. Bijker, F. Iachello, A. Leviatan
The algebraic treatment of baryons is extended to strange resonances. Within this framework we study a collective string-like model in which the radial excitations are interpreted…
Cluster states in nuclei as representations of a U(n+1) group
R. Bijker, F. Iachello
We propose a description of cluster states in nuclei in terms of representations of unitary algebras U(n+1), where n is the number of space degrees of freedom. Within this framewor…

R. Bijker, F. Iachello, A. Leviatan
We study strong decays of nonstrange baryons by making use of the algebraic approach to hadron structure. Within this framework we derive closed expressions for decay widths in an…

R. Bijker, F. Iachello, A. Leviatan
We study the electromagnetic form factors of the nucleon in a collective model of baryons. Using the algebraic approach to hadron structure, we derive closed expressions for both e…
