Au-analyte adducts resulting from single massive gold cluster impacts

Utilizing Au400 4+ primary ions produces large molecular ion yields, some in excess of unity, with minimal surface damage. A surprising observation is the occurrence of Au-analyte adducts as part of the ejecta desorbed by a single Au-cluster impact.We present data that demonstrate that Au and Au-adducts as secondary ions (e.g., AuCN , AuGly and AuCsI ) are the result of the interaction between a single primary ion, Au400 4+ and the target atoms
