  The production cross-section of $^{68}$Ge, $^{69}$Ge, $^{65}$Zn and $^{67}$Ga
radioisotopes from alpha-induced nuclear reaction with $^{nat}$Zn have been
measured using the stacked foil activation technique followed by the off-line
$\gamma$-ray spectroscopy in the incident alpha energy range 14-37 MeV. The
obtained nuclear reaction cross-sections are compared with previous
experimental data available in the EXFOR data library, evaluated nuclear data
from TENDL-2019 and theoretical results, calculated using TALYS nuclear
reaction code. We have also performed the detailed uncertainty analysis for
these nuclear reactions and their respective correlation metrics are presented.
Since $\alpha$-induced reactions are important in nuclear medicine and
developing the nuclear reaction codes so needful corrections related to the
coincidence summing factor and the geometric factor have been considered during
the data analysis in the present study.
