Abstract
The first evidence for excited states in $\chem{^{95}Ag}$ is presented. $\chem{^{95}Ag}$ is the heaviest Tz=1/2 nucleus for which gamma-rays have been identified. The reaction $\chem{^{40}{Ca}}$( $\chem{^{58}{Ni}}$, 1p2n) $\chem{^{95}Ag}$ was used in the experiment, which resulted in the assignment of three gamma-rays to $\chem{^{95}Ag}$. A detector system consisting of the detector arrays Euroball, Neutron Wall and Euclides was used to detect gamma-rays, neutrons and charged particles, respectively.
