Gamma-ray coincidence spectra presented by Vo {ital et} {ital al}. [Phys. Rev. C {bold 50}, 1713 (1994)] may indicate the existence of a positron ({ital e}{sup +}) transition with a maximum decay energy of (15.9{plus_minus}1.2) keV. Possible sources of spurious coincidences, mimicking the {ital e}{sup +} signal, are discussed and, where possible, calculated or estimated. Considerable systematic uncertainty remains in estimating the noise coincidence rate; hence, the existence of this {ital e}{sup +} transition is not established. Another {ital e}{sup +} transition with a maximum decay energy of 243 keV has been identified for the first time. {copyright} {ital 1996 The American Physical Society.}
