【 摘 要 】

We report evidence for interference phenomena beyond Young-type in electron emission spectrum from the dimers by fast ions. Prior measurements for H2have led to a wide discussion for which no definitive conclusions have been settled, whereas theoretical-side have failed to reproduce the phenomenon. The process under investigations is treated by using a nonperturbative semi-classical approach to solve the time-dependent Schrodinger equation. Our results are supported by an analytic model based on second- and third-order Born series.
