Time-differential perturbed angular correlation (TDPAC) spectroscopy is a nuclear solid-state technique that requires high energy and coincidence-time resolutions from scintillation crystals and photodetectors. Traditionally, photomultiplier tubes (PMTs) have been coupled to LaBr 3 :Ce crystals; however, they have been replaced by Multi Pixel Photon Counters (MPPCs) for TDPAC experiments conducted under external magnetic fields. In this report, we show that, for TDPAC spectroscopy, the performan
