General Comments:

1994Cz02: 66Co produced by fragmentation of a 500 MeV/u 86Kr beam on a Be target and fragment separator. Measured T1/2.

1994Se12: activity produced by fragmentation and fission reactions of 800-MeV proton beam incident on a natural Th target and time-of-flight isochronous (TOFI) spectrometer. Measured mass

1988Bo06, 1985Bo49: activity produced by bombardment of natural W target with 11.4 MeV/u projectiles of 76Ge and an on-line mass separator. Measured Eγ, Iγ, β-γ, γγ coincidences and T1/2.

1998Gr14: activity produced by 86Kr projectiles on a target of natural Ni, E=542 MeV. GANIL Laboratory. Measured γ rays, γγ coin, γ-particle coin. Detectors: Hyperpure Ge, Si planar detectors.
