Q(β-)=1.9×103 keV SYS(n)= 6.4×103 keV SYS(p)= 9.9×103 keV SYQ(α)= -7.E2 keV SY
Reference: 2012WA38

General Comments:

Activity produced by bombarding targets of tungsten and tantalum with 1.5-GeV 176Yb projectiles. Activity assigned to 174Er by mass separation and Tm K-x rays observed in the β- decay of this isotope (1989Ch05,1991Be04).
