Abstract:
Unknown β-delayed proton precursor 135Gd has been synthesized by the reaction 106Cd ( 32S, 3n ) and identified using a helium-jet recoil fast tape-transport system with a γ(X)-p coincidence measurements. Its β-delayed proton spectrum has been observed. The half-life of 135Gd decay has been determined to be 1.1 ± 0.2 s.
