A new isomeric <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:mrow><a:mo>(</a:mo><a:msup><a:mn>4</a:mn><a:mo>−</a:mo></a:msup><a:mo>)</a:mo></a:mrow></a:math> state at 285.5(32) keV in <b:math xmlns:b="http://www.w3.org/1998/Math/MathML"><b:mmultiscripts><b:mi>Tb</b:mi><b:mprescripts/><b:none/><b:mn>162</b:mn></b:mmultiscripts></b:math> was reported by Orford [] based on a Penning-trap mass measurement. Here, we show that this result is not compatible with existing experimental data. The state identified as <c:math xmlns:c="http://www.w3.org/1998/Math/MathML"><c:mmultiscripts><c:mi>Tb</c:mi><c:none/><c:mi>m</c:mi><c:mprescripts/><c:none/><c:mn>162</c:mn></c:mmultiscripts></c:math> with a mass-excess value of <d:math xmlns:d="http://www.w3.org/1998/Math/MathML"><d:mrow><d:mo>−</d:mo><d:mn>65593.9</d:mn><d:mo>(</d:mo><d:mn>25</d:mn><d:mo>)</d:mo></d:mrow></d:math> keV is actually the <e:math xmlns:e="http://www.w3.org/1998/Math/MathML"><e:msup><e:mn>1</e:mn><e:mo>−</e:mo></e:msup></e:math> ground state. The state identified as the ground state of <f:math xmlns:f="http://www.w3.org/1998/Math/MathML"><f:mmultiscripts><f:mi>Tb</f:mi><f:mprescripts/><f:none/><f:mn>162</f:mn></f:mmultiscripts></f:math> is most likely a molecular contaminant with the same mass-over-charge ratio.
