Abstract

The weak line of Hg ii located at 5677.10 Å is used to measure the mercury abundance in two mercury rich stars, HD 35548 and HD 89822. The synthesis of this line, using the current atomic parameters available in NIST, confirms that mercury is very abundant in both stars. The abundance derived from this line is in very good agreement with the abundance derived from the commonly used line at 3983.93 Å for HD 35548 but it is smaller for HD 89822.
