In this paper we study some aspects of the K L 0 elastic scattering as well as of the K S 0 regeneration on nuclei. In particular, the radial localization of these processes and their sensitivity to neutron densities are discussed.
Using aligned Na 23 beams, fusion cross sections σ fus and second-rank tensor analyzing powers for fusion T 20 fus have been measured at energies near and below the fusion barrier for 23 Na + 48 Ti and for 23 Na + 206 Pb. At sub-barrier energies, large, nearly maximal, values of T 20 fus occur,...
Cross sections for photon elastic scattering have been measured for U 238 between 4.8 and 6.4 MeV with an energy resolution of about 50 keV. These data have been used along with existing photofission data to infer the total photoabsorption cross section σ T and the fission transmission...
We have explored the viability of incoherent np γ bremsstrahlung as the dominant mechanism for the production of high energy γ rays in heavy-ion collisions by comparing the calculated relative angular distributions with experimental results. We have utilized the Boltzmann master equation model...
The S 2 factors of He 3 + Λ 9 Be and α + Λ 8 Be decays from the S -substitutional state of C 1 Λ 2 are evaluated by assuming SU 3 wave functions. The unknown hypernucleus, the lifetime of which was measured, is identified as Be Λ 9 .
Levels in 136 , 138 , 140 Sm were populated by the beta decay of Eu, following (HI,p x n) reactions and on-line mass separation. The beta decay of Eu 136 with a half-life of 3.9(±0.5) s was observed for the first time. Members of the γ band were observed in all three daughter nuclei....
The origin of the oscillations in the fusion excitation function for the 12 C + 12 C system is investigated in the framework of the optical model using the concept of internal and barrier waves. It is found that the oscillations are caused by the interference of internal and barrier waves, which...
We have observed incomplete momentum transfer in binary reactions of the 40 Ar + 58 Ni system at 15 MeV/nucleon with a relative intensity of 0.11±0.05 . The projectile spectator has a mass close to A=8 , and the inelasticity of reactions with incomplete momentum transfer is halfway between that...
Proton-induced spallation reactions are studied in the energy region from 300 MeV to 20 GeV. An analytical expression is derived for the production cross sections of target residues in which the incident proton energy dependence of the cross sections is described by variation of a single...
A general Poincaré invariant potential model for two-particle systems is constructed within the framework of light front dynamics. The model specifies all ten of the generators that are necessary to satisfy the Poincaré algebra. Formal expressions for the scattering states are constructed, and...
