Structure of P and Si in a two-level shape-coexistence model
A. O. Macchiavelli, H. L. Crawford, C. M. Campbell +7
Exclusive cross sections for the PSi reaction to the lowest and states, measured at NSCL with GRETINA and the S800, are interpreted in terms of a two…
Coriolis coupling effects in proton-pickup spectroscopic factors from B
A. O. Macchiavelli, H. L. Crawford, R. M. Clark +9
Spectroscopic factors to low-lying negative-parity states in Be extracted from the B(,He)Be proton-removal reaction are interpreted within the rotationa…
Effects of Magnetic Fields on HPGe Tracking Detectors
I. Y. Lee, A. O. Macchiavelli
We present a study of magnetic fields effects on the position resolution and energy response of hyper-pure germanium detectors. Our results provide realistic estimates of the poten…
The Core of F in the Rotational Model
A. O. Macchiavelli, R. M. Clark, H. L. Crawford +6
In a recent experiment, carried out at RIBF/RIKEN, the FO reaction was studied at 270 MeV/A in inverse kinematics. Derived spectroscopic factors suggest that…
Understanding the Low-Energy Enhancement of the -ray Strength Function of Fe
M. D. Jones, A. O. Macchiavelli, M. Wiedeking +27
A model-independent technique was used to determine the -ray Strength Function (SF) of Fe down to -ray energies less than 1 MeV for the first time with GRETINA usin…
Structure of 29F in the Rotation-aligned Coupling Scheme of the Particle-Rotor Model
A. O. Macchiavelli, P. Fallon, H. L. Crawford +6
Recent results from RIKEN/RIBF on the low-lying level structure of 29F are interpreted within the Particle-Rotor Model. We show that the experimental data can be understood in the…
Analysis of Spectroscopic Factors in 11Be and 12Be in the Nilsson Strong Coupling Limit
A. O. Macchiavelli, H. L. Crawford, C. M. Campbell +6
Spectroscopic factors in 10Be, 11Be and 12Be, extracted from (d,p), one neutron knockout, and (p,d) reactions are interpreted within the rotational model. Assuming that the ground…
Unexpected distribution of strength in the calcium isotopes at =30
H. L. Crawford, A. O. Macchiavelli, P. Fallon +30
The calcium isotopes have emerged as an important testing ground for new microscopically derived shell-model interactions, and a great deal of focus has been directed toward this r…
Nuclear Structure Towards N=40 60Ca: In-beam gamma-ray Spectroscopy of 58,60Ti
A. Gade, R. V. F. Janssens, D. Weisshaar +28
Excited states in the neutron-rich N=38,36 nuclei \nuc{60}{Ti} and \nuc{58}{Ti} were populated in nucleon-removal reactions from \nuc{61}{V} projectiles at 90~MeV/nucleon. The γ-ra…
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…
