    "abstract": "We report on a theoretical calculation and a new experimental determination\nof the 1s3p ^3P_J fine structure intervals in atomic ^4He. The values from the\ntheoretical calculation of 8113.730(6) MHz and 658.801(6) MHz for the nu_{01}\nand nu_{12} intervals, respectively, disagree significantly with previous\nexperimental results. However, the new laser spectroscopic measurement reported\nhere yields values of 8113.714(28) MHz and 658.810(18) MHz for these intervals.\nThese results show an excellent agreement with the theoretical values and\nresolve the apparent discrepancy between theory and experiment.",
