Using time information in μLCR spectroscopy: Older muons are wiser

ForμLCR with slow polarization transfer, the weak resonance signals can be strengthened by delaying the positron observation period, for pulsed and chopped muon beams. Furthermore, the sensitivity to drifts can be reduced or eliminated by using the ratios of late to earlye+ counts. These possibilities for using time information are discussed quantitatively.
