Popis: We report on the hyperfine-structure measurements of the 5P{sub 1/2} and 5P{sub 3/2} states as well as the isotope shift of the D{sub 1} transition of radioactive {sup 82}Rb (t{sub 1/2}=75 s) atoms trapped in a magneto-optical trap. The systematic effects of light shift (ac Stark shift) and power broadening were explored to verify the accuracy of our trap and probe method against saturation spectroscopy results in {sup 85}Rb. The hyperfine-splitting magnetic-dipole coefficient (A) for the {sup 82}Rb 5P{sub 1/2} state and the isotope shift of the D{sub 1} transition ({delta}{nu}{sup 82-85}) was measured to be 122.7(1.0) MHz and -150.8(2.0) MHz, respectively. The hyperfine splitting for the {sup 82}Rb 5P{sub 3/2} state was determined to be 90.3(1.5) MHz in agreement with the previous measurement of 89.3(9.0) MHz [C. Thibault et al., Phys. Rev. C 23, 2720 (1981)]. These measurements provide key information that is needed to manipulate and determine the polarization of trapped {sup 82}Rb atoms for a parity violating {beta}-asymmetry measurement.
