The available experimental data for the <n:math xmlns:n="http://www.w3.org/1998/Math/MathML"> <n:mrow> <n:msubsup> <n:mn>2</n:mn> <n:mn>1</n:mn> <n:mo>+</n:mo> </n:msubsup> <n:mtext>−</n:mtext> <n:msubsup> <n:mn>4</n:mn> <n:mn>1</n:mn> <n:mo>+</n:mo> </n:msubsup> <n:mtext>−</n:mtext> <n:msubsup> <n:mn>6</n:mn> <n:mn>1</n:mn> <n:mo>+</n:mo> </n:msubsup> <n:mtext>−</n:mtext> <n:msubsup> <n:mn>8</n:mn> <n:mn>1</n:mn> <n:mo>+</n:mo> </n:msubsup> </n:mrow> </n:math> multiplet are compared with shell-model calculations based on the well-established Kuo-Herling interaction. The new <o:math xmlns:o="http://www.w3.org/1998/Math/MathML"> <o:mrow> <o:mi>B</o:mi> <o:mo>(</o:mo> <o:mi>E</o:mi> <o:mn>2</o:mn> <o:mo>)</o:mo> <o:mo>↓</o:mo> </o:mrow> </o:math> value agrees well with the shell-model prediction, providing evidence that the properties of the <p:math xmlns:p="http://www.w3.org/1998/Math/MathML"> <p:msubsup> <p:mn>2</p:mn> <p:mn>1</p:mn> <p:mo>+</p:mo> </p:msubsup> </p:math> and <q:math xmlns:q="http://www.w3.org/1998/Math/MathML"> <q:msubsup> <q:mn>8</q:mn> <q:mn>1</q:mn> <q:mo>+</q:mo> </q:msubsup> </q:math> states of <r:math xmlns:r="http://www.w3.org/1998/Math/MathML"> <r:mmultiscripts> <r:mi>Pb</r:mi> <r:mprescripts/> <r:none/> <r:mn>210</r:mn> </r:mmultiscripts> </r:math> can be consistently described together within the nuclear shell-model framework.
