(American Physical Society, 2010)Expressing explicitly the parameters of the standard Skyrme interaction in terms of the macroscopic properties of asymmetric nuclear matter, we show in the Skyrme-Hartree-Fock approach that unambiguous correlations exist ...
-
(American Physical Society, 1991)Relative dielectronic-recombination cross sections for hydrogenlike argon are presented. The contributions of the KLL, KLM, KLN, KLO, and KLP groups of resonances are compared to theoretical calculations. The experimental ...
-
(American Physical Society, 2007)We present a microscopic treatment of current-induced torques and thermal fluctuations in itinerant ferromagnets based on a functional formulation of the Keldysh formalism. We find that the nonequilibrium magnetization ...
-
(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 ...

(American Physical Society, 1997)The giant resonance region in Ca-40 was studied with inelastic scattering of 240 MeV alpha particles at small angles including 0 degrees. A peak at E-x = 17.5 +/- 0.4 MeV with Gamma = 4.95 +/- 0.25 MeV was found to contain ...

(American Physical Society, 1998)The giant resonance region in Si-28 was studied with inelastic scattering of 240 MeV alpha particles at small angles including 0 degrees. The giant resonance peak extended from E-x=12 MeV to 35 MeV and E0 strength corresponding ...

(American Physical Society, 2000)The strength distribution of the giant monopole resonance in Ni-58 has been measured from E-x = 10 to 35 MeV using small-angle scattering of 240-MeV alpha particles. E0 strength corresponding to 74(-12)(+22)% of the E0 ...

(American Physical Society, 2009)Giant resonances in (116)Sn were measured by inelastic scattering of (6)Li ions at E(6)Li=240 MeV over the angle range 0(degrees)-6(degrees). Isoscalar E0-E3 strength distributions were obtained with a double folding model ...
