$sup 141$Pr($gamma$,n) CROSS SECTION FROM THRESHOLD TO 24 MeV.

The $^{141}\mathrm{Pr}(\ensuremath{\gamma},n)$ cross section was measured from threshold to 24 MeV with a photon beam produced by the in-flight annihilation of positrons. The photon beam resolution was determined to be 1.2% (full width at half maximum) by elastically scattering the $\ensuremath{\gamma}$ rays from the 15.1-MeV level in $^{12}\mathrm{C}$. The ($\ensuremath{\gamma},n$) cross section was found to have a maximum value of \ensuremath{\sim}348 mb and an integrated value up to 24 MeV of 1.72 \ifmmode\pm\else\textpm\fi{} 0.16 MeV b. Within the statistics and the photon resolution of the measurement, the results indicate that there is no structure in the cross section, with the possible exception of a weak bump at approximately 17.5 MeV. The results are compared with previous measurements and with theory; the latter comparison indicates that the widths of states in the dynamic collective theory should be considerably broader than those which have been typically used.
