Probing molecular photophysics in a matter-wave interferometer

We show that matter-wave diffraction off a single standing laser wave can be used as an accurate measurement scheme for photophysical molecular parameters.These include state-dependent optical polarizabilities and photon-absorption cross sections, the relaxation rates for fluorescence, internal conversion, and intersystem crossing, as well as ioniz

Water quality in three potential drought refuges in an arid-land river: assessing habitat suitability for at-risk fish species

Drought is a common disturbance in arid-land streams and rivers.The survival of aquatic species depends on access to refuge habitats where water quality remains high.Over the past century, modified flow regimes and altered watershed and instream characteristics have led to the extinction and endangerment of numerous fish species endemic to the QUER
