C110100100010 DETECTOR (NAICR) C110100100011 PART-DET (XR) C110100100012 METHOD (ACTIV,STTA,CHSEP) Following irradiation, polonium C110100100013 was chemically separated from the target and catcher C110100100014 foils by spontaneous deposition on silver. The C110100100015 radioactivity of the 207Po product was assayed with C110100100016 thin NaI(Tl) X-ray detectors. C110100100017 ANALYSIS (DECAY) The decay curves were analysed with the CLSQ C110100100018 least-squares program. C110100100019 ERR-ANALYS (DATA-ERR,10.,15.) The random errors in both the C110100100020 cross-section and range values are estimated as C110100100021 10-15%, being comprised primarily of the uncertainty C110100100022 in target thickness.

The C110100200006 target material consisted of highly enriched C110100200007 206Pb (97.4%). The recoil catchers were prepared of C110100200008 very pure (99.999%) aluminum foil having a surface C110100200009 density of 5 mg/cm2. Stacks consisting of six C110100200010 target-catcher pairs were mounted in a target holder C110100200011 which also served as a Faraday cup for determination C110100200012 of the beam intensity.
