中微子-铁散射探测超新星中微子

Detection of supernovae neutrinos with neutrino-iron scattering

A. R. Samana, C. A. Bertulani

摘要:

在投影准粒子无规相近似下计算了$ν_e-^{56}$ Fe的截面。这个模型解决了RPA中观察到的质量在$^{12}$ C附近的原子核的难题,因为它是唯一正确处理泡利原理的RPA模型。的截面作为入射中微子能量的函数进行了比较与最近的理论计算类似的模型。用通量谱加权后的平均截面与实验数据吻合较好。计算了LVD探测器探测超新星中微子的预期事件数,得出了在本实验中特别重要的电子中微子能量的上限

英文摘要:

The $ν_e-^{56}$Fe cross section is evaluated in the projected quasiparticle random phase approximation (PQRPA). This model solves the puzzle observed in RPA for nuclei with mass around $^{12}$C, because it is the only RPA model that treats the Pauli principle correctly. The cross sections as a function of the incident neutrino energy are compared with recent theoretical calculations of similar models. The average cross section weighted with the flux spectrum yields a good agreement with the experimental data. The expected number of events in the detection of supernova neutrinos is calculated for the LVD detector leading to an upper limit for the electron neutrino energy of particular importance in this experiment
