146EU c The {+146}Eu level scheme from {+146}Gd |e decay is that proposed by
146EU2c 1981Ka07 on the basis of |g, |g|g, (X-ray)|g coin. It differs from the
146EU3c earlier proposed schemes by repositioning in the cascade of coincident
146EU4c |g rays: the 114.7 keV level decays by the 114.7 keV transition and
146EU5c the 230.2 keV level decays by 115.5 keV transition. Such a sequence is
146EU6c supported by the measurements of (p,2n) reactions and {+146}Gd |e
146EU7c decay (2013Bh07). The analysis of the 2013Bh07 data shows that the
146EU8c work is done with a poor energy calibration
146EU d The experimental data of 2013Bh07 do not agree well with the proposed
146EU2d level scheme: calculation of energy levels using the program GTOL
146EU3d gives a normalized |h{+2}=12. Energy of the |g-transitions included in
146EU4d the level scheme are less on 0.63 - 1.11 keV than adopted data. The
146EU5d sum of energy values of a cascade transitions and a corresponding
146EU6d crossover transition show poor energy calibration:
146EU7d 114.06+114.88=228.94 (7), but E=229.40 (3) for a crossover transition;
146EU8d 114.88+153.86=268.74 (5), E=268.96 (6) for a crossover transition.
