with mono-energetic proton beams of 165 MeV and
224 MeV, respectively. Results acquired by means of trans-
versal PGS at different phantom depths, ranging from 6 cm
before the Bragg peak (BP) to 3.5 cm beyond the BP in 5 mm
steps with a 1 cm slit collimation (tungsten) showed a slight
decrease of PG yields after the BP. Similar measurements
with a semi-opened collimation configuration demonstrated a
steeper decrease of PG yields after the BP.

The present work continues our research program
on lanthanide halide-alkali metal halide systems. We
focused our studies on these systems for two rea-
sons: Firstly, rare-earth metals play a significant role
in sophisticated industrial applications. Secondly, data
