215PO c 2003Ku26: {+215}Bi produced by {+232}Th(p,X) and {+238}U(p,X) at
215PO2c 1 GeV proton energy, followed by mass separation. Measured E|g, I|g,
215PO3c |a, |g|g, |b|g coin, |a|g coin, |g x ray coin using large Ge detector
215PO4c for |g-rays, low-energy Ge detector for x rays and low-energy |g rays,
215PO5c plastic scintillator for |b.
215PO c 2004DeZV: estimated |b feeding to the ground state
215PO c See also evaluation of this decay scheme by the Decay Data Evaluation

215PO C 1990RU02: 215BI mass-separated source produced by spallation of 200-MEV
215PO2C protons on targets of 232TH. Measured EG, RI, GG coin, BG coin.
215PO3C Detectors: 4PI plastic scintillator, GELI.
215PO cB IB,LOGFT$ Except for the strongly populated level at 293.5 keV, all
215PO2cB other values should be considered as limits (upper for I|b and lower
215PO3cB for log| {Ift} values), since the level scheme is likely incomplete
215PO4cB above the excitation energy of 1400 keV. The I|b feedings given here
215PO5cB are deduced from |g-intensity balances based on 10% {I10} |b feeding
215PO6cB to g.s. Values listed in 2003Ku26 are given under comments
215PO cG RI$ In table 3 of their paper, 2003Ku26 state that gamma intensities
215PO2cG are in percent per decay, but this is inconsistent with their decay
215PO3cG scheme in their figure 6. The intensities quoted in table 3 of 2003Ku26
215PO4cG are relative intensities, instead, as communicated in a priv. comm. of
215PO5cG April 2011 from J. Kurpeta (first author of 2003Ku26) to evaluator

215PO3CB an approach which is "approximate and of highly questionable merit" as
