The p-4He elastic differential cross section has been measured at a kinetic energy of 2.68 GeV. The momentum transfer region studied is t = 0.15–0.66 (GeV/c)2. The cross section displays a shallow first minimum and shape very similar to recent data at 1 GeV. 相似文献

The Feynman path integral Monte Carlo approach has been coupled to the gauge including atomic orbital formalism in order to analyse the absolute magnetic shieldings of the benzene nuclei under the conditions of thermal equilibrium. The Hamiltonian employed in the derivation of ensemble averaged NMR quantities is of the Hartree-Fock type. The basis set used is of 6–31G quality. The spatial delocalization of the atoms leads to a deshielding of both types of benzene nuclei relative to the shieldings experienced at the minimum of the potential energy surface. This deshielding has to be traced back to bond length elongations in thermal equilibrium. The influence of the nuclear fluctuations on the NMR parameters of benzene is quantum driven up to temperatures of 400 K; classical fluctuations are of minor importance in this low-temperature window. 相似文献

The total reaction cross section for 16O + 16O has been measured at six energies between Ec.m. = 6.8 and 11.9 MeV. Cross sections for the production of protons, alphas, neutrons, deuterons, 31S, 30P, 12C(g.s.) + 20Ne(g.s.) and the relative γ-yield were obtained with a variety of experimental methods. No 3H or 3He were found. All cross sections are normalized to 16O + 16O elastic scattering at θc.m. = 90°, which was measured separately with high precision between Ec.m. = 7.3 and 14.4 MeV. The elastic scattering and relative γ-yield of 12C + 12C were measured between Ec.m. = 3.9 and 7.5 MeV. The elastic scattering and neutron yield of 12C + 16O were measured between Ec.m. = 5.4 and 10.1 MeV. 相似文献
