The alpha decay of {sup 181--186}Au and {sup 181--185}Pt has been studied utilizing sources from an on-line isotope separator. The {alpha} decay of {sup 185}Pt and {sup 186}Au was observed for the first time and several new {alpha} groups were observed for the decay of {sup 181--185}Au. By simultaneous measurement of {gamma}-rays and x-rays and use of known ec/{beta}+ decay schemes, {alpha}-decay branching ratios and hindrance factors were deduced for each {alpha} transition. Several previously unknown low-lying {gamma}-ray transitions were observed in the Ir daughters by means of {alpha}-{gamma} coincidence measurements.
