VIENNA, Austria (AP) _ These are the more prominent Nazi war criminals known or presumed to be still alive but never brought to account in countries where alleged crimes were committed during World War II. The information was obtained from Simon Wiesenthal's Documentation Center in Vienna, the West German Center for Investigation of National Socialist Crimes and Associated Press files.

HEINRICH MUELLER - This head of the German Gestapo and overseer of the Nazi's extermination program would be 85 years old if still alive. In the immediate postwar years he was said to have fled to Albania and then further east. His family, however, said he had died after the war and that he was buried in Berlin under a gravestone bearing his name. In 1964, West German officials said after an exhumation that examinations of the remains were inconclusive.

ALOIS BRUNNER, 73 - A chief aide to Adolf Eichmann, the architect of the Nazi master plan for the mass extermination of Jews who was executed in Israel in 1962. Brunner still lives in Damascus, Syria, according to West German justice officials, who failed to win his extradition from Syria as recently as December 1984. A native of Austria, Brunner was sentenced to death in absentia in 1954 in France for crimes against humanity. Nazi hunter Beate Klarsfeld alleges he was responsible for the death of at least 100,000 Jews.

ROLF GUENTHER, 72 - An Eichmann deputy who investigators charge was involved in many of Eichmann's crimes. His whereabouts are unknown.

ANTON BURGER, age unavailable - Another Eichmann assistant and deputy commander of the Theresienstadt (Terezyn) concentration camp in Czechoslovakia. He was caught and imprisoned but escaped in 1948 and all trace of him has been lost, according to the Jewish Documentation Center in Vienna.

LEON DEGRELLE, 79 - Belgium's top war criminal, he lives in Spain and has Spanish citizenship. He led a Belgian SS unit on the Eastern front and was sentenced to death after the war in Belgium. The Belgians failed in several attempts to gain his extradition during the years of the Franco government in Spain and now the statute of limitations has since run out in his case. In 1974, the Belgian government banned Degrelle from Belgium on the grounds that his return would create trouble.

ROBERT JAN VERBELEN, 74 - A leader of a Flemish SS unit in Belgium and reportedly Degrelle's deputy for a time, Verbelen lives in Vienna as a naturalized Austrian citizen. He was sentenced to death in absentia by a Belgian military court in 1947. The Belgian government failed in an extradition attempt in the early 1960s while Austria was conducting an pre- trial investigation of his wartime activities. After a three-week trial, an Austrian court acquitted him in December 1965 of charges of murdering seven Belgian resistance fighters. Verbelen now is protected by an Austrian prohibition on the extradition of its own citizens.
