70CU c {+70}Ni activity produced in proton-induced fission of natural
70CU2c uranium, with E(p)=30 MeV. Fission fragments first thermalized and
70CU3c neutralized in a buffer gas then selectively extracted through
70CU4c resonant laser ionization and electromagnetic separation using the
70CU5c LISOL separator. Measured E|g, I|g, |g|g, |b|g, and |g(t) using two
70CU6c HPGe detectors and a thin plastic |DE scintillator. Subset of results
70CU7c presented in 2004Va07. See also 2002VaZX, thesis.
70CU c A total energy release of 3520 keV {I180} is calculated for this
70CU2c decay scheme using the RADLST code, which can be compared to the
70CU3c total Q value of 3762.5 keV {I24}. Due to the |?1.8 MeV gap in
70CU4c energy between the highest observed excited level and the Q value and
70CU5c also the approximation that has gone into the normalization of the
70CU6c decay scheme, beta-decay feeding intensities and log {Ift} values
70CU7c should be considered approximate.
70CU cG E,RI$From 2004Va08. I|g are given relative to I|g(1036|g)=100.
70CU cG M$From the Adopted Levels.
70CU cG E(A)$Ordering of the 650|g-386|g cascade and the 233|g-386|g cascade
70CU2cG could not be determined. A reverse ordering resulting in the 628-keV
70CU3cG level moving to 892.5 keV and the 706-keV level moving to 553.5-keV
70CU4cG is also possible.
70CU cL E$From a least-squares fit to E|g, by the evaluators.
