Theory of first-order layering transitions in thin helium films
(American Physical Society, 1996)
Thin liquid He-4 films on graphite show evidence of layered growth with increasing number density via a succession of first-order phase transitions. These so-called ''layering transitions'' separate uniformly covering ...
l-forbidden Gamow-Teller beta decay of Cu-57
(American Physical Society, 1996)
Absolute branching ratios for the beta decay of Cu-57 to excited states up to 3.3 MeV in Ni-57 have been determined, including the rho-forbidden Gamow-Teller transition to the first excited state in Ni-57. Four transitions ...
Gamow-Teller strength of Mg-26
(American Physical Society, 1996)
We have measured cross sections for (d,He-2)-induced reactions on Mg-26 at an energy of E(d)=125.2 MeV. The measured Gamow-Teller strength is significantly smaller than that inferred from (p,n) reactions. We demonstrate ...
Low-lying levels in Cu-57 and the rp process
(American Physical Society, 1996)
The level scheme of Cu-57 is investigated via the H-1(Ni-58,Cu-57-gamma)2n reaction by using the recoil mass spectrometer MARS at the Texas AandM Cyclotron Institute. Three low-lying excited states are observed in Cu-57 ...
np-elastic analyzing power A(N0) at 485 and 788 MeV
(American Physical Society, 1996)
Measurements are reported for the np-elastic analyzing power from 30 degrees to 128 degrees c.m., at 485 and 788 MeV, with a typical precision of 0.005 and absolute accuracy of 2%. Results strengthen the isospin-0 phase-shift ...
Pion flow and antiflow in relativistic heavy-ion collisions
(American Physical Society, 1996)
Within the framework of a relativistic transport model (ART 1.0) for heavy-ion collisions at AGS energies we study the transverse flow of pions with respect to that of nucleons using two complementary approaches. It is ...
Dilepton production from resonance scattering in hot hadronic matter
(American Physical Society, 1996)
Dilepton production from resonance scattering in hot hadronic matter is studied. Including the widths of these resonances, which enhance the phase space for dilepton production, we find that the production rate is significantly ...
Kaon dispersion relation and flow in relativistic heavy-ion collisions
(American Physical Society, 1996)
Within the framework of a relativistic transport model (ART) for heavy-ion collisions at AGS energies, we examine the effects of a kaon dispersion relation on the transverse flow of kaons and their transverse momentum and ...
