Lifetime Measurements for the First 2+ States in 162, 164Gd Populated by the β Decay of 162, 164Eu

Lifetimes of the first 2+ states in 162, 164Gd have been measured by means of β—γ delayed coincidence technique for mass‐separated 162Eu and 164Eu isotopes. Using the obtained lifetimes τ(162Gd) = 3.98(8) ns and τ(164Gd) = 4.0(2) ns, B(E2;0+□2+) values were deduced as B(E2;0+□2+) (162Gd) = 5.45(11) e2b2 and B(E2;0+□2+) (164Gd) = 5.2(3) e2b2.
