摘要：

Using ultrafast time-resolved IR spectroscopy, we measure the transition from the populated 1s state to the 2p state of the yellow excitonic series of Cu2O. We show that this technique can provide information on the populations of n = 1 ortho- and paraexcitons, their distribution in momentum space, their interconversion rate, as well as their expansion through the crystal.
