204TL3C  photons; GE(LI) detector with 2.7-KEV resolution at 662 KEV; data
204TL4C  collected in 16 ^15-|ms intervals for G(T) measurement.
204TL C  1972Ma59: isomer populated by 204HG(D,2NG); thick liquid 204HG target;
204TL2C  E(D)=15 MEV; 2-|ms beam pulses at 250-|ms intervals, data collected
204TL3C  during 17- to 180-|ms interval after beam pulse; GE(LI) detector.

204TL DG CC$ FROM BrIcc v2.2 (31-Mar-2008) 2008KiAA, "Frozen Orbitals" appr.
204TL CG E$From 1975Uy01; others: 1958Du80, 1962Eu01. 1958Du80 confirm the
204TL2CG coin between 414.1G and 689.9G, but the ordering was not determined.
204TL DG RI$From 1958Du80 ----- was originally I(414)/I(690)=1.14...  --------
204TL CG M$From analogy with 198TL, 202TL. Consistent with A2>0 (values not
204TL2CG specified) for 414.1G and 689.9G in G(THETA) by 1972Ma59.
204TL CG M(A)$1958Du80 placed an upper limit of 0.2 on the ratio of total
204TL2CG number of conversion electrons from the 414.1- and 689.9-keV
204TL3CG transitions, as determined by x-ray yield, to the 414.1G intensity,
204TL4CG i.e. [^N{-e}(689.9)+^N{-e}(414.1)]/^N{-|g}(414.1) LE 0.2. This limit is
204TL5CG consistent with the ICC's for the assigned multipolarities.
204TL CL E$From a least-squares fit to EG, unless otherwise specified
204TL CL J$From adopted levels.
204TL DL J$By analogy with 198TL, 202TL. Consistent with G(THETA) in 1972Ma59.

204TL CL $MOMM1 = +1.187 6 by 1972Ma59, but not corrected for Knight shift or
