The E802 Spectrometer at the Brookhaven Alternating Gradient Synchrotron has been used to measure the correlations in relative momentum between like-sign pions emitted in central Si+Al and Si+Au collisions at 14.6{ital A} GeV/{ital c}. Data are presented in terms of the correlation function for both identified {pi}{sup {minus}} and {pi}{sup +} pairs near the nucleon-nucleon center-of-mass rapidity. All parametrizations of the correlation function are consistent with a spherically symmetric source of rms radius {ital R}{sub rms}{approx}3.5{plus minus}0.4 fm and lifetime {tau}{similar to}2 fm/{ital c}.
