我们发现，超新星中微子可以通过观察它们与100Mo的荷电相互作用来研究，100Mo具有很强的自旋-同位旋巨共振。关于电子-中微子球的有效温度和振荡成其他类型的电子中微子的信息都可以从电子(逆β)谱中提取出来。我们利用测量的强子电荷交换谱和准粒子随机位相近似计算了100Mo对超新星电子中微子的带电电流响应。用于ββ和太阳中微子研究的卫星探测器的放大版本也可能对超新星中微子的光谱研究有用。
We show that supernova neutrinos can be studied by observing their charged-current interactions with100Mo, which has strong spin–isospin giant resonances. Information about both the effective temperature of the electron–neutrino sphere and the oscillation into electron neutrinos of other flavors can be extracted from the electron (inverse β) spectrum. We use measured hadronic charge-exchange spectra and the Quasiparticle Random Phase Approximation to calculate the charged-current response of100Mo to electron neutrinos from supernovae, with and without the assumption of oscillations. A scaled up version of the MOON detector for ββ and solar-neutrino studies could potentially be useful for spectroscopic studies of supernova neutrinos as well.
