Abstract
In this study, we report preliminary results on the characterization of the presence of molecular interferences when using UOâ, UCâ and UC2â as injected molecular ions. In particular the possibility to stabilize the current yield from carbide cathodes has been investigated: it was found that the best cathode preparation procedure is obtained pressing U salts baked at 800 °C mixed with graphite and Al powder. Moreover, the 238U background in 236U measurements is strongly reduced injecting UCâ ions, as verified using a time-of-flight detection system. On the other hand, 235U interference is larger with respect to UOâ injection, but this increase is smaller than expected on the basis of abundances of 13C and 17O in UC and UC2 molecules on one side and UO, on the other.
