    "abstract": "We report on a consistent, microscopic calculation of the bound and\nscattering states in the 4He system employing a realistic nucleon-nucleon\npotential in the framework of the resonating group model (RGM). We present for\ncomparison with these microscopic RGM calculations the results from a\ncharge-independent, Coulomb-corrected R-matrix analysis of all types of data\nfor reactions in the A=4 system. Comparisons are made between the phase shifts,\nand with a selection of measurements from each reaction, as well as between the\nresonance spectra obtained from both calculations. In general, the comparisons\nare favorable, but distinct differences are observed between the RGM\ncalculations and some of the polarisation data. The partial-wave decomposition\nof the experimental data produced by the R-matrix analysis shows that these\ndifferences can be attributed to just a few S-matrix elements, for which\ninadequate tensor-force strength in the N-N interaction used appears to be\nresponsible.",
