 76ZN c  {+76}Cu ion beam was produced neutron-induced fission of a             
 76ZN2c  UC{-x} target followed by ionization by RILIS using a broad-band       
 76ZN3c  laser.  A=76 was selected with a magnetic mass separator and implanted 
 76ZN4c  into the ISOLDE Decay Station (IDS).  A moving tape was positioned     
 76ZN5c  at the center of the setup.  Beta particles detected with a            
 76ZN6c  plastic scintillator in front of the tape.  Two small LaBr{-3}(Ce)     
 76ZN7c  crystals were on each side of the tape. In the first experiment,       
 76ZN8c  |g rays were measured with 4 clover-type HPGe detectors. For the       
 76ZN9c  second experiment two additional HPGe were added downstream.           
 76ZNAc  Measured E|g, I|g, |g|g, |g(t). Find no evidence for a previously      
 76ZNBc  proposed 1.27 s isomer in {+76}Cu.  Propose that isomer and            
 76ZNCc  ground state have very similar half-lives.
