 90TC c  2004De40: {+90}Ru isotope produced in the {+58}Ni({+36}Ar{+10+},
 90TC2c  2n2p) reaction with E=150 MeV. Nuclei recoiling out of the target
 90TC3c  were stopped and neutralised by 500 mbar of purified Ar gas inside a
 90TC4c  cell. Reaction products were ionized selectively, according to Z,
 90TC5c  using two dye lasers tuned to the resonant atomic transitions of the
 90TC6c  particular element. Laser-ionized nuclei were guided to the LISOL
 90TC7c  mass separator by a sextupole ion guide. Measured E|g, I|g, |g|g,
 90TC8c  |b|g (coin), I|b, isotopic T{-1/2} with two HPGe detectors arranged
 90TC9c  in a compact configuration around |b-sensitive plastic |DE detectors.

 90TC4c  Identification of {+90}Ru decay based on comparison of |s(E({+58}Ni))
 90TC5c  with cascade calculations; 37 |g-rays identified in coincidence with
 90TC6c  Tc K|a| x ray by 1994Zh26 but not placed in a decay scheme.
 90TC cE LOGFT$Values should be regarded as lower limits, as there is a large
 90TC2cE difference between the allowed energy for decay (5.8 MeV) and the
 90TC3cE highest observed excited level (0.6 MeV).
