Abstract: We present results from an experiment dedicated to measure the lifetimes of the low-lying excited states of <superscript>205</superscript>Bi. This nucleus was studied in the one-proton transfer reaction <superscript>204</superscript>Pb(<superscript>16</superscript>O,<superscript>15</superscript>N)<superscript>205</superscript>Bi and the lifetimes of the 11 / 2 1 - , 7 / 2 1 - , 5 / 2 1 - , 7 / 2 2 - states were determined by utilizing the Recoil Distance Doppler Shift method. Upon comparing the results with the expectations of the particle-core coupling model, it indicates a low quadrupole collectivity in the structure of these states. [ABSTRACT FROM AUTHOR]
