摘要:

在Be靶上测量了C12碎裂3.5 °角处氢同位素的动量谱。动量谱覆盖了碎裂最大值区域和累积区域。微分截面跨越五个数量级。将数据与四个Monte Carlo代码的预测进行比较:QMD,LAQGSM,BC和INCL++。在高动量区,一些模式的数据和预测之间有很大的差异。INCL++代码提供了对数据的最佳和几乎完美的描述。

英文摘要:

Momentum spectra of hydrogen isotopes have been measured at 3.5 deg from C12 fragmentation on a Be target. Momentum spectra cover both the region of fragmentation maximum and the cumulative region. Differential cross sections span five orders of magnitude. The data are compared to predictions of four Monte Carlo codes: QMD, LAQGSM, BC, and INCL++. There are large differences between the data and predictions of some models in the high momentum region. The INCL++ code gives the best and almost perfect description of the data.
