    "abstract": "Nonrelativistically forbidden, single-photon transition rates between low\nlying states of the helium atom are rigorously derived within quantum\nelectrodynamics theory. Equivalence of velocity and length gauges, including\nrelativistic corrections is explicitly demonstrated. Numerical calculations of\nmatrix elements are performed with the use of high precision variational wave\nfunctions and compared to former results.",
