Channeling of 3 keV H+ ions in copper

Energy spectra and angle dependent yield distributions of 3 keV H⁺ ions scattered from a (001) face of a copper single crystal were measured. The spectra reveal channeling and semi-channeling effects at this relatively low primary energy.     

Mixed states for an Allen-Cahn type equation,II

This paper continues the recent study of an Allen-Cahn model PDE [1] by eliminating a strong spatial reversibility condition and by weakening certain nondegeneracy conditions on families of basic heteroclinic solutions, enabling us to obtain multibump solutions in a much more general setting. As in [1], novel minimization arguments play a key role in finding solutions.Received: 7 April 2003, Accepted: 7 October 2003, Published online: 24 November 2003Mathematics Subject Classification (2000): 35J80, 58E30Paul H.
