68CU c 2003Ho31: {+68}Zn(n,p), E(n)=14 MeV on 99.4% enriched {+68}Zn target.
68CU2c Measured E|g, I|g, |g|g, |g|g(t) using two BaF{-2} detectors and an
68CU3c n-type Ge detector.
68CU c 1975Ti01: {+68}Zn(n,p), E(n)=14.9 MeV. Measured E|g, I|g using Ge(Li)
68CU2c detector.
68CU c 1972Sw01: {+68}Zn(n,p), E(n)=14.7 MeV on natural and enriched targets
68CU2c followed by radiochemical separation. Measured E|g, I|g, E|b, I|b,
68CU3c |g|g- and |b|g-coincidences using a Ge(Li), NaI(Tl) and plastic
68CU4c detector.
68CU c 1971Si19: {+68}Zn(n,p), E(n)=14 MeV on natural and enriched targets
68CU2c followed by radiochemical separation. Measured E|g, I|g, E|b, I|b,
68CU3c T{-1/2}, |g|g- and |b|g-coincidences using a Ge(Li) detector, NaI(Tl)
68CU4c detectors (for |g|g) and a NE102A plastic scintillator.
68CU c 1969Wa22: {+68}Zn(n,p), E(n)=14.7 MeV on natural and enriched targets
68CU2c followed by radiochemical separation. Measured E|g, I|g, E|b, I|b,
68CU3c T{-1/2}, |g|g- and |b|g-coincidences using a Ge(Li) detector, NaI(Tl)
68CU4c detectors (for |g|g) and a plastic scintillator.
68CU cL E$From a least-squares fit to E|g's by evaluator.
68CU cL J,T(a)$From the Adopted Levels.
68CU cG E$From 2003Ho31.
68CU cG RI$From 2003Ho31 relative to I(526|g)=100. I|g's are in general in
68CU2cG good agreement with prior measurements, except where noted.

68CU2cG suggest discrepancy is due to change in intensity of 80|g and 81|g in
68CU3cG {+133}Ba source used for efficiency calibration.

68CU cL J$E2 610|g to 1+. 1975Ti01 and 1972Sw01 assign the level as 3- and
68CU2cL the 610|g as M2, however, this is excluded by RUL.

68CU cG RI$Others: 1.7 {I5} (1975Ti01), 1.4 {I4} (1972Sw01). Discrepancy
