L The existence of Yb/sup 164/ with UPSILON 1/2 = 75 plus or minus 2 min, producing a daughter Tm/sup 164/ with T,1/2 = 2 plus or minus 0.5 min, was found among tanthilum spallation products. Tm/sup 164/ transforms into stable Er/ sup 164/, emitting positrons with a maximum energy of 2940 plus or minus 20 kev and gamma rays of 91.5 plus or minus 0.1 and 211 plus or minus 2 kev. Il. A decay scheme is suggested for Ir/sup 184/, with a haif life of 3.1 plus or minus 0.3 hr. A new isotope (Pt/sup 187/) with a half life of 2.0 plus or minus 0.4 hr was also found. (R.V.J.)
