Empirical signatures of shape phase transitions in nuclei with odd nucleon numbers
D. Bucurescu, N. V. Zamfir
Nuclear level density at low excitation energies is proposed as an indicator of the first order phase transitions in nuclei. The new signature, a maximum value of the level density…
Systematics of 2+ states in semi-magic nuclei
D. S. Delion, N. V. Zamfir
We propose a simple systematics of low lying 2+ energy levels and electromagnetic transitions in semi-magic isotopic chains Z=28,50,82 and isotonic chains N=28,50,82,126. To this p…
Complementary descriptions of shape/phase transitions in atomic nuclei
Dennis Bonatsos, E. A. McCutchan, N. V. Zamfir
Shape/phase transitions in atomic nuclei have first been discovered in the framework of the Interacting Boson Approximation (IBA) model. Critical point symmetries appropriate for n…
Connecting the X(5)-, X(5)-, and X(3) models to the shape/phase transition region of the interacting boson model
E. A. McCutchan, Dennis Bonatsos, N. V. Zamfir
The parameter independent (up to overall scale factors) predictions of the X(5)-, X(5)-, and X(3) models, which are variants of the X(5) critical point symmetry developed…
Anomalous behavior of the first excited 0 state in nuclei
K. Kaneko, R. F. Casten, M. Hasegawa +5
A study of the energies of the first excited states in all even-even 8 nuclei reveals an anomalous behavior in some nuclei with = , 2. We analyze…
A test of X(5) for the gamma degree of freedom
R. Bijker, R. F. Casten, N. V. Zamfir +1
We present the first extensive test of the critical point symmetry X(5) for the gamma degree of freedom, based in part on recent measurements for the gamma-band in 152 Sm. The agre…
