Fast Rotation of the N=Z Nucleus 36Ar
C. E. Svensson, A. O. Macchiavelli, A. Juodagalvis +30
A highly-deformed rotational band has been identified in the N=Z nucleus 36Ar. At high spin the band is observed to its presumed termination at I=16+, while at low spin it has been…
Collective T=0 pairing in N=Z nuclei? Pairing vibrations around 56Ni revisited
A. O. Macchiavelli, P. Fallon, R. M. Clark +9
We present a new analysis of the pairing vibrations around 56Ni, with emphasis on odd-odd nuclei. This analysis of the experimental excitation energies is based on the subtraction…
Is there np pairing in odd-odd N=Z nuclei?
A. O. Macchiavelli, P. Fallon, R. M. Clark +9
The binding energies of even-even and odd-odd N=Z nuclei are compared. After correcting for the symmetry energy we find that the lowest T=1 state in odd-odd N=Z nuclei is as bound…
Superdeformation in Po
D. P. McNabb, G. Baldsiefen, L. A. Bernstein +17
The Yb(Si,5n) reaction at 148 MeV with thin targets was used to populate high-angular momentum states in Po. Resulting rays were observed with Gammaspher…
Spin-rotor Interpretation of Identical Bands and Quantized Alignment in Superdeformed A 190 Nuclei
J. A. Cizewski, R. Bijker
The ``identical'' bands in superdeformed mercury, thallium, and lead nuclei are interpreted as examples of orbital angular momentum rotors with the weak spin-orbit coupling of pseu…
Onset of Collectivity in Neutron Deficient Po
L. A. Bernstein, J. A. Cizewski, H. -Q. Jin +30
We have studied via in-beam -ray spectroscopy Po and Po, which are the first neutron-deficient Po isotopes to exhibit a collective low-lying structure. The ratio…
