151ER c 1997Co24: {+96}Mo({+58}Ni,2pn) E=4.4~MeV/nucleon. Measured E|g, I|g,
151ER2c |g|g, ce. Mass-separated source. Conversion electrons measured with a
151ER3c mini-orange magnetic spectrometer
151ER c 1988Ba02: {+92}Mo({+64}Zn,N4P) and {+96}Mo({+58}Ni,2pn). Measured: |g,
151ER2c |g|g, X|g, ce, |gce. A total of six gamma rays were reported
151ER c 1980Ja16: {+141}Pr,{+144,}{+147}Smbarded with {+12}C, {+14}N, {+16}O
151ER2c beams of E=70-130~MeV. Measured: delayed |g|g, multiplicity, excitation
151ER3c functions. Isotopic identification from cross bombardment, excitation
151ER4c functions. 1980Bo07 assigned two isomers (45~ns~{I5} and 37~ns~{I10})
151ER5c to {+151}Er. 1980Ja16, however, give them as one isomer belonging to
151ER6c {+152}Ho on the basis that they are observed in the {+141}Pr+{+16}O
151ER7c bombardment also.

151ER c Some authors are common in 1997Co24 and 1988Ba02
151ER cG $1997Co24 state that some of the |g-transition placements by 1990Ak01
151ER2cG in {+151}Tm |e decay (4.17~s) study are in conflict with their work.
151ER3cG Apparently, the details of the work by 1997Co24 are in a thesis by R.

151ER cG RI$Deduced by the evaluator from I(|g+ce) if 1997Co24 and |a from BrIcc
151ER2cG code. Uncertainties for I(|g+ce) were not given by 1997Co24. These are
151ER3cG assumed as 2% for three (289, 1099 and 1140) strong gamma rays and
151ER4cG 5-10% for the others in comparison to those quoted in 1988Ba02, a study

151ER3cN {+151}Er from the decay of 0.58-s isomer, %I(|e+|b{++})=4.7~{I4}. Thus
151ER4cN %IT=95.3~{I4}. It should be pointed out that in the level scheme of
151ER5cN 1997Co24, the the total transition intensity feeding the g.s. is
151ER6cN 93.1~{I19}, somewhat less than the adopted %IT=95.3~{I4}, yet agrees
151ER7cN within the uncertainties.
