The 1s- and 2p(+/-)-like acceptor states in the presence of a magnetic field are then calculated variationally. The effects of the spatially dependent screening function epsilon(r) on the calculation of the transition energies are specifically investigated. The use of a constant epsilon(o) is shown to yield better agreement with experimental results.en10.1002/(SICI)1521-3951(199802)205:2<537info:eu-repo/semantics/closedAccessSpectraStatesDonorsArticle2052537542Q3WOS:000072138300015
