Resumen:
We have confirmed the existence of the
BeC62− dianion produced in a Cs-sputter
negative ion source with a cathode of mixed Be
metal and graphite powder.
Using our laser-accelerator mass spectrometry (AMS)
system, we have studied the photoelectric
interaction of the dianion and show that it
is bound by more than 1.165 eV relative to
any photodetachment or dissociation channel.
The total cross-section leading to either of
the channels for 2.33 eV photons is 6 Mb.
