Cross section measurements for $\gamma$-rays emitted in $^{109}$Ag($n, x n y p \gamma$) reactions

Absolute partial cross sections for production of discrete $\gamma$-rays using $^{109}$Ag($n, x n y p \gamma$) reactions with $x \leq 7$ and $y \leq 1$ in a total of 12 reaction channels were measured. The data were taken using the GEANIE spectrometer comprised of 20 high-purity Ge detectors with BGO escape-suppression shields. The broad-spectrum pulsed neutron beam of the Los Alamos Neutron Science Center's (LANSCE) WNR facility provided neutrons in the energy range from 1 to 300~MeV. The time-of-flight technique was used to determine the incident neutron energies. Partial $\gamma$-ray cross sections for a total of 109 transitions and for neutron energies 1~MeV$< E_{n} <$300~MeV were obtained. Five previously unknown transitions were identified, were assigned to $^{109}$Ag, and were placed in the level scheme. An estimate of the population of isomers in the ($n,n^{\prime}$), ($n,2n$) and ($n,3n$) channels was made. Theoretical calculations up to $E_{n} = 100$~MeV from the CoH$_{3}$ reaction model are compared to the experimental results.
