Isoscalar giant resonances for nuclei with mass between 56 and 60
(American Physical Society, 2006)
The giant resonance region from 10 MeV < E-x < 62 MeV in Fe-56, Ni-58, and Ni-60 has been studied with inelastic scattering of 240 MeV alpha particles at small angles, including 0 degrees. Most of the expected isoscalar ...
Giant resonances in (116)Sn from 240 MeV (6)Li scattering
(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 ...
Isoscalar electric multipole strength in C-12
(American Physical Society, 2003)
The excitation region in C-12 below E-x=45 MeV was studied using 240 MeV alpha-particle scattering. Elastic scattering was measured from theta(c.m.)=3.8degrees to 49.4degrees and density dependant folding optical model ...
Giant monopole strength in Ni-58
(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 ...
Functional Keldysh theory of spin torques
(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 ...
Laser-excited acoustic oscillations in silver and bismuth nanowires
(American Physical Society, 2007)
Coherent acoustic oscillations in Bi and Ag nanowire samples were studied with a femtosecond pump-probe technique and detection of the scattered light. The observed optical and acoustic properties reflect the nanostructure ...
Magnetization relaxation in (Ga,Mn)As ferromagnetic semiconductors
(American Physical Society, 2004)
We describe a theory of Mn local-moment magnetization relaxation due to p-d kinetic-exchange coupling with the itinerant-spin subsystem in the ferromagnetic semiconductor (Ga,Mn)As alloy. The theoretical Gilbert damping ...
Isoscalar giant dipole resonance in Zr-90, Sn-116, and Pb-208
(American Physical Society, 2001)
Strength functions for isoscalar dipole excitations in Zr-90, Sn-116, and Pb-208 have been measured with inelastic scattering of 240 MeV alpha particles at small angles. The isoscalar E1 strength distribution in each nucleus ...
Giant resonances in O-16
(American Physical Society, 2001)
Giant resonances in O-16 have been studied with inelastic scattering of 240 MeV alpha particles at small angles, Isoscalar E0, E1, and E2 strength corresponding to 48 +/- 10%, 32 +/- 7%, and 53 +/- 10%, of the respective ...
Giant resonances in Ti-46,Ti-48
(American Physical Society, 2006)
The giant resonance region from 9 MeV < E-x < 55 MeV in Ti-46 and Ti-48 has been studied with inelastic scattering of 240 MeV alpha particles at small angles including 0(degrees). Isoscalar monopole strength in Ti-46 (Ti-48) ...
