The Quasi-Elastic (QE) contribution of the nuclear inclusive electron model developed in Nucl. Phys. A627 543 (1997) is extended to the study of neutrino/antineutrino Charged Current (CC) and Neutral
Current (NC) induced nuclear reactions at intermediate energies.
Long range nuclear (RPA) correlations, Final State Interaction (FSI) and Coulomb corrections are included within the model. RPA correlations are shown to play a crucial role in the whole range (100--500 MeV) of studied neutrino energies. Results for inclusive muon capture for different nuclei through the Periodic Table are also discussed. In addition, and by means of a Monte Carlo cascade method to account for the rescattering of the outgoing nucleon, we also study the CC and NC inclusive one nucleon knockout reactions off nuclei.
The γ-ray production in neutral-current neutrino oxygen interaction in the energy range above 100 MeV
计算了中性流中微子-氧准弹性相互作用产生γ射线的截面，其中剩余核（15 N * 或15 O *）在分支比为41%时产生能量大于6 MeV的γ射线，称为$ν+\^{16}O \rightarrow ν+p+^{15}N*$或$ν+^{16}O \rightarrow ν+n+^{15}O*$.在200 MeV以上，这个截面超过了非弹性反应产生的伽马射线，$ν+^{16}O->ν+^{16}O*$。在本计算中，$1p_{1/2}, 1p_{3/2} and 1s_{1/2}$态的光谱函数和光谱因子是必不可少的。γ射线的产生主要是由剩余核的$1p_{3/2}$态的退激发所决定的。

Study of the neutrino-oxygen cross sections of the charged-current reaction 16O($\barν_e,e^+$)16N(0 MeV,$2^-$) and the neutral-current reaction 16O($ν,ν$')16O(12.97/12.53 MeV,$2^-$), producing high-energy gamma rays
Discrimination of parametrizations for nuclear effects in neutrino scattering through comparisons of low (~ 700 MeV) and medium (~ 3 GeV) energy cross-section data
Particle physics origin of the 5 MeV bump in the reactor antineutrino spectrum?
中微子物理学中最令人困惑的问题之一是反应堆反中微子光谱中5 MeV过量的起源。本文研究了有机闪烁体探测器中通过反应$^{13}$ C $(\overlineν, \overlineν^\prime n)^{12}$ C $^*$产生的过量。$^{12}$ C $^*$的去激发产生瞬发$4.4$ MeV光子，而产物中子的热化引起质子反冲，这又产生具有有限宽度的额外瞬发能量贡献。这些效应可以共同模拟能量约为5 MeV的逆β衰变事件。我们考虑了几个非标准中微子相互作用产生这样一个过程，并发现大亚湾首选的参数空间是不利的中微子诱导氘衰变和相干弹性中微子核散射的测量。虽然非最小粒子物理方案可能是可行的，但这种异常的核物理解决方案似乎更有吸引力。
