Binding Energy of aΛParticle in Nuclear Matter

The results of a complete calculation of the binding energy $D$ of a $\Lambda$ particle in nuclear matter using the method of the independent-pair approximation, which systematically take into account the second- and third-order Born corrections, are presented. It is found that these corrections are small and that the Born series converges rapidly. A comparison of our results with those obtained using other methods based on the Brueckner theory shows that they are identical.
