An accurate isochoric high-pressure measurement was made on a [sup 3]He-[sup 4]He liquid mixture at very low temperatures. The obtained data allow us to make a systematic determination of the [sup 3]He effective mass as a function of pressure and [sup 3]He concentration. The dependence is consistent with our proposed [sup 3]He-[sup 3]He quasiparticle-interaction potential, but disagrees with the result from the specific-heat measurements.
