Abstract
The high-spin structure of the $^{105}\mathrm{Ag}$ nucleus has been studied by using the $^{100}\mathrm{Mo}$($^{10}\mathrm{B}$, $5n)$$^{105}\mathrm{Ag}$ reaction to search for chiral doublet bands based on the three-quasiparticle $\ensuremath{\pi}{g}_{9/2}\ensuremath{\nu}({h}_{11/2}){}^{2}$ configuration. The level scheme of $^{105}\mathrm{Ag}$ has been extended. New bands were found and the placement of the yrast $\ensuremath{\pi}{g}_{9/2}\ensuremath{\nu}({h}_{11/2}){}^{2}$ band was corrected. No side band to the yrast $\ensuremath{\pi}{g}_{9/2}\ensuremath{\nu}({h}_{11/2}){}^{2}$ band could be found in the present experiment. This observation indicates that the \ensuremath{\gamma}-soft shape in the $^{106}\mathrm{Ag}$ changed to a more \ensuremath{\gamma}-rigid axially symmetric shape in the yrast $^{105}\mathrm{Ag}$ configuration. However, a new pair of bands was observed to show the expected properties of a chiral doublet structure.
