Human Factors
We were on an IFR flight plan in Aircraft X. We were talking to BTR Approach on 120.3 as they were vectoring us for the ILS 13 approach. The copilot was the pilot flying. We were descending through 5400 ft. when we exited a cloud and the copilot spotted two motorized hang gliders approximately 200 feet below us. The copilot immediately arrested the descent in order to avoid the hang gliders. The copilot alerted ATC of the traffic at that position. They apparently were not squawking a transponder code because ATC did not alert us and we were not painting them on our traffic system. We landed Baton Rouge without incident.
Captain reported an NMAC event with two powered hang gliders that did not show up on radar during approach to BTR airport.
