    "abstract": "We investigate the helium atom embedded in a superstrong magnetic field\ngamma=100-10000 au. All effects due to the finite nuclear mass for vanishing\npseudomomentum are taken into account. The influence and the magnitude of the\ndifferent finite mass effects are analyzed and discussed. Within our full\nconfiguration interaction approach calculations are performed for the magnetic\nquantum numbers M=0,-1,-2,-3, singlet and triplet states, as well as positive\nand negative z parities. Up to six excited states for each symmetry are\nstudied. With increasing field strength the number of bound states decreases\nrapidly and we remain with a comparatively small number of bound states for\ngamma=10^4 au within the symmetries investigated here.",
