 76CU c  {+76}Cu isotope was produced by bombarding natural U target            
 76CU2c  with protons at E=35 MeV. Fission fragments stopped and thermalized    
 76CU3c  in helium gas, extracted from the gas cell, guided through a SPIG,     
 76CU4c  then accelerated to 30 keV and mass separated with a 55|' dipole       
 76CU5c  magnet.  Measured mass excess using the double Penning trap JYFLTRAP   
 76CU6c  using the ToF-ICR technique.  Deduced excitation energy of isomer.
