Atlanta also posted a 97-83 win at Philadelphia on January 29 and a 114-105 triumph at the First Union Center last Friday, 114-105.
The Hawks come off consecutive losses, including a tough, 102-99 overtime setback at Detroit on Wednesday when the Pistons’ Chauncey Billups nailed a 3-pointer from the top of the arc just before the buzzer.
The Sixers slipped 1 1/2 games behind Atlantic Division-leading New Jersey with a 102-98 home loss to Golden State on Friday.
Allen Iverson had 28 points and 10 assists, Keith Van Horn 18 points and Kenny Thomas 12 and a season-high 18 rebounds fore the Sixers, who trailed by 25 points in the third quarter before rallying to within two points before falling short down the stretch.
The Sixers, who are an Eastern Conference-best 20-16 on the road, are 10-3 away from the First Union Center since the All-Star break.
