1989Vi04: 135Eu produced in the reaction 92Mo(46Ti,p2n) E=192 MeV and mass separated through on-line techniques. Measured x rays, γ rays, positrons and T1/2. 135Eu identified by Sm x rays and Sm x β+ coincidences. No delayed proton activity was assigned by 1989Vi04, the authors state that interfering delayed protons from the daughter 135Sm may have obscured a possible weak proton branch from the decay of 135Eu
Decay scheme of 135Eu to 135Sm is not known, except that a weak 120.8γ associated with 135Eu decay was assigned (1989Vi04) from Sm x-γ coincidences.
