164TM C 1982ADZZ: Measured E|g, I|g, ce, I(x rays). Previous work from
164TM2C the same laboratory: 1972GRYR (also 1975GR44), 1965AB05, 1960DA16,
164TM3C 1960AB05
164TM C 1971DE22: Measured E|g, I|g, |g|g coin
164TM C 1997ZAZW: Measured ce for nine |g rays
164TM c 2001AlZU: studied {+164}Yb |e decay using a constant-field magnetic
164TM2c |b-ray spectrograph, and report ce lines for previously
164TM3c unreported |g rays with energies of 29.03-, 37.44-, 65.22-,
164TM4c 69.95-, 120.60- and 122.29-keV, but give no other information
164TM C The proposed level scheme is considered as tentative.
164TM c Problem about the Q(|e) value needs to be resolved.
164TM cE $RADLST code gives a total absorbed energy of 1097 keV {I3}.
164TM CE IE From intensity balance at each level.
