Angular distribution of dissociated deuterons by impact of 2–16-MeVO8+

Abstract

The angular distributions of dissociated deuterons for electron capture and ionization by bare oxygen ions with energies from 2 to 16 MeV in collision with molecular deuterium targets were measured. The dependence of the differential cross sections on the alignment of the molecular axis with respect to the beam axis was determined. The results show that in the transfer ionization and transfer excitation processes, the deuterium molecules are more likely to be aligned perpendicular to the incident beam than parallel to the beam. This feature can be qualitatively interpreted as resulting from the interference of capture amplitudes from the two atomic centers. In the double ionization and ionization excitation processes, little alignment dependence was observed.PACS number(s): 34.70.+ e, 34.50.Gb

Young-Type Interference in Collisions between Hydrogen Molecular Ions and Helium

“…The above theoretical work and subsequent experimental work, however, showed that other global observables show traces of this interference [9][10][11][12][13].…”

Two-Center Interferences in Dielectronic Transitions inH2++HeCollisions

“…Only recently, the predictions of Tuan and Gerjuoy were confirmed by several experiments. Variations of the capture cross sections as a function of the molecular orientation could be attributed to interference effects [2][3][4][5]. Later, Schmidt et al [6] observed very pronounced matter wave interference fringes in multiple differential momentum spectra of recoil ions produced in dissociative capture in H þ 2 þ He collisions.…”

Evidence of Wave-Particle Duality for Single Fast Hydrogen Atoms

“…Following Deb et al [21], Wang et al [19], and Shingal and Lin [22] derived equivalent theoretical cross section variations with the H 2 target orientation. Their predictions were recently confirmed for 0.3-1.3 MeV H þ þ H 2 collisions [23], while no direct observation of interference in the outgoing projectile wave was possible in [23] or in the only similar work [24].…”
