Momentum spectra of $\pi\sp-$, $K\sp-$, p and d have been measured from central collisions of 14.6 $\times$ A GeV/c Si beam on Si and W targets at rapidity 1.9 $<$ y $<$ 2.1. The inverse slope parameters $T\sb0$ obtained by an exponential fit with the transverse mass spectra in transverse kinetic energy are found to be $T\sb0(\pi\sp-) < T\sb0(K\sp-) < T\sb0(p) < T\sb0(d)$. This result is predicted by a radially expanding flow model. From integrated results, the $K\sp-/\pi\sp-$ ratios, (2.7 $\pm$ 0.3) % from Si and (2.4 $\pm$ 0.2) % from W, are consistent with pp collision results. The deuteron production rates can be explained by a relativistic coalescence model.
