Gas D402900100012 cells (2.cm diam. and 2.5 cm length) having 200 micronsD402900100013 of Al windows were used as targets. In the case of D402900100014 99.9% enriched Xe-124 5 target cells were filled D402900100015 simultaneously up to 0.48 bar. In the case of 20% D402900100016 enrichment the irradiated gas was transferred into an D402900100017 evacuated gas container via cryogenic technics.

The primary incident proton energies were 45, D402900100033 30,3, 24, 22.5 and 20 MeV. The cells were irradiated D402900100034 for 5min at 200 nAmp beam current. The beam intensity D402900100035 was measured by using Faraday-cup as well as monitor D402900100036 reactions. The radiocesium was separated for a few D402900100037 cells filled with 20% enriched Xe-124. The radioiodine D402900100038 was separated for a few cells filled with 99.9% D402900100039 enriched Xe-124.
