171YB c  {+171}Tm activity from the decay of {+171}Er which was produced        
171YB2c  through thermal neutron irradiation of an 98.1% isotopically enriched  
171YB3c  {+170}Er target followed by chemical separation.                       
171YB4c  Measured E|g, I|g using HPGe detector. Deduced absolute                
171YB5c  intensity of 66.7-keV transition using |g spectroscopy and             
171YB6c  and inductively coupled mass spectrometry. Reference sources of        
171YB7c  {+60}Co and {+44}Ti/{+44}Sc in equilibrium were used.
