177YB c  Mass-separated {+177}Tm activity was produced by {+136}Xe (1.22, 1.59  
177YB2c  GeV), {+186}W (2.17, 2.79 GeV), and {+238}U (2.71 GeV) projectiles on  
177YB3c  targets of natural tungsten and tantalum. Assignment of this activity  
177YB4c  to {+177}Tm was based on the observation of the known 104.5 and 227 |g 
177YB5c  rays in {+177}Yb. Authors mentioned an alternative (though unlikely)   
177YB6c  assignment of the activity to a possible 85-s isomer in {+177}Yb.      
177YB7c  Measured E|g, I|g, |b|g coin, |g|g coin. Detectors: plastic            
177YB8c  scintillator for |b{+-}, Ge(Li) for |g rays and x rays.
