Abstract
The current integrating technique has been implemented using a CdWO4 s cintillator mounted onto a 28x28 mm(2) PIN photodiode. With this metho d we were able to measure count rates an order of magnitude higher tha n commonly used in Mossbauer spectroscopy, and down to count rates as low as 500 000 per second. Very small Pr-141 Mossbauer resonance absor ption effects could at 4.2 K be detected (approximate to 10(-4)), some of them amongst the smallest ever to be recorded. As an example we sh ow the Pr-141 Mossbauer spectrum of PrCu2Si2 at 4.2 K.
