87ZR c Although the strongest decay branch has probably been reported,
87ZR2c since the decay energy is over 5 MeV and only levels below
87ZR3c 350 keV have been observed, higher energy states should be
87ZR4c expected.
87ZR c 1974Vo03: spallation by 660-MeV protons on silver and chemical
87ZR2c separation; measured: |g singles and |g|g coincidences with
87ZR3c parent activity separated by T{-1/2} for each |g ray.
87ZR c 1986CoZQ: {+58}Ni({+32}S,3p), E({+32}S)=110 MeV; measured |g singles
87ZR2c and |g|g coincidences
87ZR c 1977Ko05: {+58}Ni({+32}S,n2p){+87}Mo and {+58}Ni({+32}S,3p){+87}Nb,
87ZR2c E=111 MeV; measured |g singles and |g|g coincidences.
87ZR c 1971Do01: {+58}Ni({+32}S,3p), E({+32}S)=90-100 MeV; measured |g singles
87ZR c 1972Tu03: {+90}Zr(p,4n); measured |g singles and |g|g coincidences.
87ZR cL J From {+87}Zr Adopted Levels.
87ZR cG E Weighted average from 1974Vo03, 1977Ko05, and 1972Tu03.
87ZR cG RI From I{-|g}(1+|a)=100 for each |g ray. This gives
87ZR2cG I{-|g}(135)/I{-|g}(201)=0.282, which compares favorably to
87ZR3cG the measured value of 0.285 {I8} (1972Tu03); others: 0.20 {I5}
87ZR4cG (1971Do01) and 0.27 {I3} (1974Vo03). No significant |e feeding
87ZR5cG is expected to the ground state and the 201 level since they
87ZR6cG would be unique 3rd forbidden and 3rd forbidden,
87ZR7cG respectively, with expected log{Ift} values of |? 21 and |? 17
87ZR8cG (1998Si17), compared to the allowed transition to the 335 level.
