Measurement of x-ray-x-ray and x-ray—γ-ray coincidence yields indicates that two to three K x rays are emitted, on the average, during the deexcitation of neutron-poor Tl and Pb isotopes populated by (6Li,xn) reactions. Experimental constraints suggest that approximately two x rays arise from a narrow region of spin (12≲J≲20) dominated by low-energy M1 transitions. Measurement of the singles yield as well as the mean multiplicity of the K x rays provides a useful new method for determining absolute evaporation-residue cross sections.
