Gross shell structure at high spin in heavy nuclei
M. A. Deleplanque, S. Frauendorf, V. V. Pashkevich +2
Experimental nuclear moments of inertia at high spins along the yrast line have been determined systematically and found to differ from the rigid-body values. The difference is att…
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…
Search for Strange Matter by Heavy Ion Activation
M. C. Perillo Isaac, Y. D. Chan, R. Clark +12
We present the results of an experimental search for stable strange matter using the heavy ion activation technique. We studied samples of a meteorite, terrestrial nickel ore, and…
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…
