  "main_findings": "Using a quasi-classical particle concept and derived energy-uncertainty formula applied to a GaAs/GaAlAs quantum well in an electric field, calculated exciton energy level widths were reported to agree with measured results. The differing effects of perpendicular versus parallel electric fields on exciton optical absorption in the quantum well were stated to be explainable by the model.",

    "Study appears to be a theoretical/modeling and materials-physics application rather than a biological/health study; no health outcomes are reported.",
