Double electron capture in 156Dy, 162Er and 168Yb
The double electron capture half-lives of 156Dy, 162Er and 168Yb are
evaluated using the pseudo SU(3) model, which describes ground and excited
bands as well as their B(E2) and B(M1) transition strengths in remarkable
agreement with experiment. The best candidate for experimental detection is the
decay 156Dy -> 156Gd, with tau{1/2} (0+{gs} --> 0+{gs}) = 2.74 E22 yrs and
tau{1/2} (0+{gs} --> 0+{1}) = 8.31 E24 yrs.Comment: 7 pages, 1 figure. Physics Letters B, in pres
