In a series of {sup 48}Ti bombardments of {sup 144}Sm the decay energy of the {sup 189}Bi{sup m} ({pi}s{sub 1/2}) {alpha} transition that proceeds to the {pi}s{sub 1/2} ground state of {sup 185}Tl was measured to be 7.30(4) MeV. This result establishes the excitation energy of {sup 189}Bi{sup m} as 190(40) keV rather than the adopted 92(10)-keV value. Our data thus indicate a leveling off in excitation energy at N {approx} 106 for the s{sub 1/2} intruder state in odd-A Bi isotopes.
