98ZR c 2006Si36: {+98}Zr isomer was produced in {+239}Pu(n,F|g) reaction using
98ZR2c thermal neutrons from high-flux reactor of the ILL, Grenoble. Fission
98ZR3c fragments were selected based on mass-to-ionic charge using the
98ZR4c Lohengrin mass spectrometer and detected using an ionization chamber;
98ZR5c |g rays were detected with a Clover Ge detector and three single Ge
98ZR6c crystals. Measured E|g, I|g, |g|g-coin, |g|g(t) relative to the arrival
98ZR7c of the fission fragments. Deduced levels, J, |p,
98ZR8c half-life, band structure, configuration. Decay of a 1.9-|ms high-spin
98ZR9c isomer studied in this work. Also 2007Si16 conference paper from the
98ZRac same group

98ZR2cG the listed uncertainty of 0.1 or 0.2 keV gives a poor fit.

98ZR cL E$2006Si36 suggest that this level is most likely different from
98ZR2cL a 16+ level at 6539.8 decaying by a 950|g proposed by 2004Wu08,

98ZR cG E$2006Si36 discussed another scenario for the placement of 63.0|g:
98ZR2cG two closely-spaced 63.0-keV gamma rays, an E1 to 6540, (16+) level
98ZR3cG (from 2004Wu08) and E2 to 6541, (15-) level. Based on intensity-balance
98ZR4cG arguments, this scenario is considered unlikely.
