The Aharonov-Bohm effect in conical space
Conical space emerges inevitably as an outer space of any topological defect
of the vortex type. Quantum-mechanical scattering of a nonrelativistic particle
by a vortex centred in conical space is considered, and effects of the
transverse size of the vortex are taken into account. Paradoxical peculiarities
of scattering in the short-wavelength limit are discussed.Comment: 17 pages, 2 figures, minor change
Role of the Nuclear and Electromagnetic Interactions in the Coherent Dissociation of the Relativistic Li Nucleus into the H + He Channel
The differential cross section in the transverse momentum and a total
cross section of mb for the coherent dissociation of a 3-A-GeV/
Li nucleus through the HHe channel have been measured on emulsion
nuclei. The observed dependence of the cross section is explained by the
predominant supposition of the nuclear diffraction patterns on light (C, N, O)
and heavy (Br, Ag) emulsion nuclei. The contributions to the cross section from
nuclear diffraction ( MeV/) and Coulomb MeV/)
dissociations are calculated to be 40.7 and 4 mb, respectively.Comment: ISSN 0021-3640, Pleiades Publishing, Ltd., 200
