    Research output: Contribution to journalArticlepeer-review


    We have studied the geometry and resonances of the e +He( 3S e) system in the framework of hyperspherical coordinates. A model potential proposed by us is used to describe the interaction between the out electron with the He + ionic core. The calculated binding energy and expectation distance of the system are in agreement with other calculations. In addition, two resonances below the e +He(1s3s 3S e) threshold and one resonance below the Ps(n=2)He + threshold are identified. � 2012 IOP Publishing Ltd.
