heal.abstract	We consider a second order periodic system with an indefinite linear part and a potential function which is superquadratic but does not satisfy the AR-condition. Using Morse critical groups, we show that the system has at least one nontrivial solution. (C) 2009 Elsevier Ltd. All rights reserved.	en
