76NI c 2015So23: measured half-life of (8+) isomer by |g(t)
76NI c 2012Ka36: {+76}Ni isomer produced in {+9}Be({+238}U,X) at
76NI2c 345 MeV/nucleon using BigRIPS separator at RIKEN facility. Measured
76NI3c delayed |g rays and isomer half-life. Total of 11000 {+76}Ni
76NI4c fragments detected
76NI c 2014Ra20: {+76}Ni isotope produced in fragmentation of {+86}Kr beam in
76NI2c a {+9}Be target at E=140 MeV/nucleon. Reaction products selected
76NI3c according to their momentum over charge ratio using the A1900
76NI4c spectrometer at NSCL-MSU facility. Measured E|g, I|g, |g|g, |g-fragment
76NI5c coin, with the NSCL beta-counting system, Si strip detector used for
76NI7c particle detection and Ge detectors for |g rays
76NI c 2005Ma59 (also 2005Gr29): {+76}Ni isomer produced in the
76NI2c fragmentation of {+86}Kr beam on {+9}Be
76NI3c target at E=140 MeV/nucleon. Reaction products selected according to
76NI4c their momentum/charge ratio using the A1900 spectrometer of the
76NI5c National Superconducting Cyclotron Laboratory (NSCL).
76NI6c Measured E|g, I|g, |g|g, |g(fragment) coin, time-of-flight and |DE with
76NI7c the NSCL double-sided Si strip detector (DSSD) and the SeGA array of
76NI8c Ge detectors. Total of 1315 fragments of {+76}Ni detected
76NI c 2004Sa13: {+76}Ni isomer produced in the fragmentation of {+86}Kr
76NI2c beam on Ta target at E=58 MeV/nucleon at GANIL. Measured E|g, I|g,
76NI3c (particle)|g coin, deduced half-life of the isomer in {+76}Ni
76NI d 2003GrZZ is superseded by 2004Sa13
76NI cG E$Weighted average of values from 2014Ra20 and 2012Ka36,
76NI2cG energy uncertainty of 0.5 keV in 2012Ka36 is mainly systematic, while
76NI3cG the statistical uncertainty is much smaller. Evaluators assume that
76NI4cG 2014Ra20 have included systematic uncertainties
76NI cG RI$From 2014Ra20. Values in 2005Ma59 are nearly the same, except
76NI2cG as noted
76NI cL J$Comparisons with shell-model calculations (2005Ma59)
76NI cL BAND(A)$Yrast band.
76NI2cL No experimental evidence (in 2005Ma59) for the existence of expected
76NI3cL 12+ or 14+ isomers

76NI cL T$from |g(t) method, weighted average of values from the four
76NI2cL transitions (2015So23). Previous (less precise) measurements:
76NI3cL 636 ns {I90} (2014Ra20), 409 ns {I+58-50} (2012Ka36);
76NI4cL 0.59 |ms {I+18-11} (2005Ma59); 0.24 |ms {I8} (2004Sa13).
76NI5cL Weighted average of above values, except seemingly discrepant result
76NI6cL from 2004Sa13, is 547.4 ns {I52}
