Description
The investigation of the decay dynamics of liquids and solutions after
x-ray irradiation became accessible in recent years owing to the
tremendous progress in liquid microjet techniques. This method meets
the high vacuum conditions required for experiments using x-ray excitation
at synchrotron radiation facilities. Mainly via electron spectroscopy,
several non-local de-excitation processes and intermolecular
interaction mechanisms were identified. Their role in radiation biology
is currently lively discussed. However, the detection of charged particles
as a probe for decay mechanisms is constrained due to their short
escape length in dense media. We present a complementary experimental
method in which fluorescence detection is used to investigate
reaction products after excitation of liquid microjets with synchrotron
radiation. This approach is especially beneficial to track neutral and
long-living species.
