  In the present study we have measured the excitation functions for the
nuclear reactions $^{100}$Mo($\alpha$,n)$^{103}$Ru,
$^{nat}$Mo($\alpha$,x)$^{97}$Ru, $^{nat}$Mo($\alpha$,x)$^{95}$Ru,
$^{nat}$Mo($\alpha$,x)$^{96g}$Tc, $^{nat}$Mo($\alpha$,x)$^{95g}$Tc and
$^{nat}$Mo($\alpha$,x)$^{94g}$Tc in the energy range 11-32 MeV. We have used
the stacked foil activation technique followed by off-line gamma ray
spectroscopy technique to measure the excitation functions. In this study we
have also documented detailed uncertainty analysis for these nuclear reactions
and their corresponding covariance matrix are also presented. The excitation
functions are compared with the available experimental data from EXFOR data
library and the theoretical prediction from TALYS nuclear reaction code. The
present measurements are found to be consistent with the available experimental
data.
