The depopulation of Ta-180m by Coulomb excitation was investigated. The rec
oiling tantalum ions from bombardments with S-36 and with Ni-64 were collec
ted in catcher foils surrounding the beam. The out-of-beam identification o
f the 8h decay of Ta-180gs in these foils leads to the existence of a media
ting state at about 1.3 MeV excited from Ta-180m by an E3 transition of the
order of several Weisskopf units.
