摘要
The angular distributions of the fragments such as <sup>7</sup>Be,<sup>24</sup>Na and <sup>28</sup>Mg pro-duced in the 600 MeV <sup>40</sup>Ar+<sup>197</sup>Au reaction are measured using off-line γ-rayspectroscopy technique.After subtraction of the contribution of fission process,thewidth σ<sub>p</sub> of the transverse momentum distribution is extracted from the analysis of thefragment angular distribution data in the framework of the projectile fragmentationmechanism.The results are compared with the calculated values of Goldhaber statisticalmodel.
