Compound-Nucleus Decay via the Emission of Heavy Nuclei
L. G. Sobotka,M. L. Padgett,G.J. Wozniak,G. Guarino,A. J. Pacheco,L.G. Moretto,Yang-Hao Chan,R. G. Stokstad,I. Tserruya,S. Wald +9 more
TL;DR: The typical compound-nucleus decay populates two distinct mass regions as mentioned in this paper, and the two decay processes have been generally considered to be also quite different, as indicated even by their names.
Journal ArticleDOI
Angular momentum misalignment in deep inelastic processes and angular distribution of sequentially emitted particles and gamma rays
TL;DR: In this paper, the angular momentum misalignment for fragments produced in deep inelastic scattering is discussed in terms of the thermal excitation of angular-momentum-bearing modes in the intermediate complex.
Journal ArticleDOI
Rise and Fall of the Spin Alignment in Deep-Inelastic Reactions
G.J. Wozniak,R. J. McDonald,A. J. Pacheco,C.C. Hsu,D. J. Morrissey,L. G. Sobotka,L.G. Moretto,S. Shih,C. Schück,R.M. Diamond,H. Kluge,F.S. Stephens +11 more
TL;DR: In this paper, the magnitude and alignment of the transferred angular momentum in the reaction {sup 165}Ho + [sup 165]Ho have been measured as a function of Q value via continuum {gamma}-ray multiplicity and anisotropy techniques.
Journal ArticleDOI
Rigid Rotation and l-Wave Fractionation in the Deep-Inelastic Reaction: 664-MeV 84Kr + natAg
L. G. Sobotka,C.C. Hsu,G. J. Wozniak,G. U. Rattazzi,R. J. McDonald,A. J. Pacheco,L.G. Moretto +6 more
TL;DR: In this article, out-of-plane angular distributions have been measured for sequential alpha decay from target-like fragments produced in fully damped heavy-ion collisions Fragment spins were extracted from the angular distributions as a function of mass asymmetry.
Journal ArticleDOI
Evidence for spin fluctuations in the deep-inelastic reaction 165Ho + 165Ho at 8.5 MeVamu
R. J. McDonald,A. J. Pacheco,G.J. Wozniak,H.H. Bolotin,L.G. Moretto,C. Schück,S. Shih,R.M. Diamond,F.S. Stephens +8 more
TL;DR: In this article, the magnitude and alignment of the transferred angular momentum in the reaction 165Ho + 165Ho have been measured as a function of Q-value via continuum γ-ray multiplicity and anisotropy techniques.
