    "abstract": "We present an investigation on the resonances of a doubly excited helium atom\nin a strong magnetic field covering the regime B = 0-100 a.u. A\nfull-interaction approach which is based on an anisotropic Gaussian basis set\nof one-particle functions being nonlinearly optimized for each field strength\nis employed. Accurate results for a total of 17 resonances below the threshold\nof consisting of He+ in the N=2 state are reported in this work. This includes\nstates with total magnetic quantum numbers M=0,-1,-2 and even z-parity. The\ncorresponding binding energies are compared to approximate energies of\ntwo-particle configurations consisting of two hydrogen-like electrons in the\nstrong field regime, thereby providing an understanding of the behavior of the\nenergies of the resonances with varying field strength.",
