SAMPLE     The thin bismuth layer (3-5-mum) of 10*50-mm area was  O127500100008 
           evaporated onto a light (7.5-g) aluminum backing.      O127500100009 
           The backing was then released from the target holder   O127500100010 
           and used directly for astatine separation via dry      O127500100011 
           distillation.                                          O127500100012

           (IOCH) The At-211 activity was subsequently measured   O127500100014

METHOD     (INTB) The intensity of the beam varied between 10 and O127500100017 
            30-micro-amperes.                                     O127500100018

COMMENT    -By authors. The overall separation yield of At-211 wasO127500100021 
           found to be 65-75%. The activity of at-211 left in the O127500100022 
           target was less than 10%. The most serious losses were O127500100023 
           probably due to deposition of astatine on the colder   O127500100024 
           part of the quartz tube. Separation was finished withinO127500100025 
           2-hours after EOB.                                     O127500100026

COMMENT    -By authors. The At-211 activity was calculated via    O127500200012 
           an 897.80-KeV gamma line of Po-211 and the At-210      O127500200013 
           activity via its 1181.39-KeV gamma line.               O127500200014 
           Presented data are average for 10 measurements.        O127500200015
