The dependence of $^{102mg}$Ag, $^{104mg}$Ag and $^{105mg}$Ag isomer ratios from energy of protons

The isomeric ratios in reactions $^{102}$Pd($p,n$)$^{102mg}$Ag, $^{104}$Pd($p,n$)$^{104mg}$Ag, $^{105}$Pd($p,n$)$^{105mg}$Ag are measured. The isomeric ratios for $^{105mg}$Ag were also obtained in reactions $^{103}$Rh ($α,2n$). For $^{105mg}$Ag the isomeric ratios were calculated on the basis of the statistical theory within the framework of the Fermi - gas, independent pairing of particles and superconductor models. For the spin cutoff parameter σ we obtained the values: 3,3±O,4($^{102mg}$Ag); 3,5±0,5($^{104mg}$Ag) и 4,0±0,5($^{105mg}$Ag). For $^{105mg}$Ag we obtained best agreement between the analytic and experimental values of isomeric ratios in the independent particle pairing model at density parametera $α =(А/8)$ MeV$^{-1}$, and in the superconductor model at $α =(А/6)$ МэВ$^{-1}$. The energy of excitation dependence of isomeric ratios confirms the value of spin (equal to two) for isomers $^{102mg}$Ag and $^{104mg}$Ag, previously established from decay models.
