摘要: The yields of neutral (H or D) negatively charged (H- D-) fragments per atom the same species have been measured in incident diatomic molecular beams. These result from break-up thin carbon foil and over a wide range thicknesses for energies 0.5, 0.7 0.9 MeV u-1. Compared with those H+ D+ beams at corresponding conditions, these can differ considerably unity. Both enhancement production neutrals inhibition negative ions exhibit dependence on reduced mass chemically equivalent systems. observed isotopic corroborates some simple models commonly put forward to explain anomalous yields.
