44Ti的丰度和分布告诉我们核坍缩超新星爆炸的本质。有必要了解产生和破坏44钛的核反应网络，以便将其用作爆炸机制的探针。44Ti(α，p)47V反应是一个非常重要的反应，它控制着44Ti的破坏。直接测量的困难导致了间接研究这种反应的尝试。在此，提出了间接研究的第一步，即鉴定化合物核48Cr的水平。一束100 MeV的质子束入射到50Cr靶上。在50Cr(p，t)48Cr反应中，48Cr中的态被填充。在iThemba实验室的K600 Q2D磁谱仪上对三子进行了动量分析。
The abundance and distribution of 44 Ti tells us about the nature of the core-collapse supernovae explosions. There is a need to understand the nuclear reaction network creating and destroying 44 Ti in order to use it as a probe for the explosive mechanism. The 44 Ti (α, p) 47 V reaction is a very important reaction and it controls the destruction of 44 Ti. Difficulties with direct measurements have led to an attempt to study this reaction indirectly. Here, the first step of the indirect study which is the identification of levels of the compound nucleus 48 Cr is presented. A 100-MeV proton beam was incident on a 50 Cr target. States in 48 Cr were populated in the 50 Cr (p, t) 48 Cr reaction. The tritons were momentum-analysed in the K600 Q2D magnetic spectrometer at iThemba LABS.
