| Abstract: | The excitation energies of the single-particle normal and intruder levels in both 183Tl and 187Bi were measured for the first time via the α decay of 187Bi produced in the 97Mo(92Mo,pn)187Bi reaction. The previously unobserved 187Bi ground state (h9/2) to 183Tl ground state (s1/2) α transition was identified, establishing the 187Bi intruder state excitation energy to be 112(21) keV, 70 keV less than that of the same level in 189Bi.
