Hybridized excitations that comprise of well-known and well-understood collective modes have received increasing interest as the possible origin of novel functionalities and unconventional materials properties.
Recently, TOF spectroscopy on CeCuAl3 has provided putative evidence for a so-called vibronic mode – a combined crystal field - phonon excitation. We have found such excitation in single crystalline samples of CeAuAl3 during a short test experiment on PANDA (despite recent TOF study on polycrystals claiming the opposite).We propose to determine the details of that excitation as well as its temperature dependence down to 3 K.
