摘要：

A comparative study of the secondary ion signals (I-n+, n = 1,2) for the N-2(+) - Ge and N-2(+) - Si ion-target combinations under varying bombardment conditions has been undertaken. Only the former reveals anomalous Ge2+ emission I2+/I+(Ge) > 1) over a wide range of primary energy (E) and target current densities (J(p)). A possible explanation has been sought. This work is actually a follow-up of our previous works carried out in search of anomalous emission of multicharged ions for various ion-target combinations.
