52CR c 1977Ya08: chemically separated sources from {+51}V(n,|g),
52CR2c measured E|g, I|g, a Compton suppression spectrometer system,

52V cP J |b|g-circular polarization rules out J({+52}V)=2 and is
52V 2cP consistent with J=3 (1967Bl10).

52CR cG 1976Ar13 reported this |g with a relative intensity of 0.22
52CR2cG {I5}. There is no evidence for a 1213-keV |g in the Compton
52CR3cG suppressed Ge(Li) spectra of 1977Ya08. This, and the apparent
52CR4cG absence of a 766-keV |g, claimed by 1976Ar13 to feed a level at
52CR4cG 2647 keV, lead evaluators to doubt that the 2647-keV level is
52CR5cG detectably populated.

52CR cG RI authors give I|g=0.088 in their table iv and I|g=0.008 in
52CR2cG their drawing. From adopted branching from 2768 level,
52CR3cG one expects I|g=0.010
52CR G 1333.62 3 0.588 10E2 C
52CR cG E authors' value of 1332.62 given in table iv is a misprint.

52CR G 766.0 10 ?
52CR cG 1976Ar13 claim to have observed the 766|g with an intensity
52CR2cG |?1.3 times that of the 647.5. The Compton suppressed
52CR3cG Ge(Li) spectra of 1977Ya08 demonstrate this is in error.
52CR4cG 1978Be32 consider no evidence for 766|g in these spectra, and
52CR5cG estimate I|g(766)/I|g(647) can not be greater than 0.05.
