Abstract: This Letter reports on the first results from the Taiwan Axion Search Experiment with a Haloscope, a search for axions using a microwave cavity at frequencies between 4.707 50 and 4.798 15 GHz. Apart from the nonaxion signals, no candidates with a significance of more than 3.355 were found. The experiment excludes models with the axion-two-photon coupling $|{g}_{a\ensuremath{\gamma}\ensuremath{\gamma}}|\ensuremath{\gtrsim}8.1\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}14}\text{ }\text{ }{\mathrm{GeV}}^{\ensuremath{-}1}$, a factor of eleven above the benchmark Kim-Shifman-Vainshtein-Zakharov model, in the mass range $19.4687<{m}_{a}<19.8436\text{ }\text{ }\ensuremath{\mu}\mathrm{eV}$. It is also the first time that a haloscope experiment places constraints on ${g}_{a\ensuremath{\gamma}\ensuremath{\gamma}}$ in the mass region of $19.4687<{m}_{a}<19.7639\text{ }\text{ }\ensuremath{\mu}\mathrm{eV}$, reaching a sensitivity 3 orders of magnitude better than the limits obtained by nonhaloscope experiments.
