直接反应中的介质效应

Medium effects in direct reactions

M. Karakoc, C. Bertulani

摘要:

本文讨论了核子-核子(NN)截面的介质修正及其对中能$\gtrsim 50$ MeV/核子直接反应的影响。与自由NN截面得到的结果进行了比较与Pauli阻塞的几何处理和NN截面与Dirac-Bruecker方法得到的。我们表明,介质修正可能会导致相当大的修改碰撞在中间能量,它们是更明显的反应,涉及弱束缚核。

英文摘要:

We discuss medium corrections of the nucleon-nucleon (NN) cross sections and their influence on direct reactions at intermediate energies $\gtrsim 50$ MeV/nucleon. The results obtained with free NN cross sections are compared with those obtained with a geometrical treatment of Pauli-blocking and with NN cross sections obtained with Dirac-Bruecker methods. We show that medium corrections may lead to sizable modifications for collisions at intermediate energies and that they are more pronounced in reactions involving weakly bound nuclei.
