近年来，我们一直在开发用于研究能量接近60 MeV的中子诱发反应的设备。 该计划的一个重要方面是发展（n，p）反应研究的能力。早期的数据范围内的原子核采取了第一次与简单的望远镜，后来与大面积多线室望远镜。最近，已经安装了磁体和双目标系统，其允许（n，p）测量低至0°。测量了~（12）C、~（13）C、~（14）C和~（90）Zr（n，p）在65 MeV下0°-40°的能谱。 ~（90）Zr数据证实了最近发现的等矢量巨共振，并提供了两个新的等矢量巨共振的证据：四极子的自旋T和同位旋T +1分量。
In recent years, we have been developing facilities for studying neutron-induced reactions at energies near 60 MeV. An important aspect of this program has been the development of capabilities for (n, p) reaction studies. Early data on a range of nuclei taken first with simple telescopes and later with large-area multiwire chamber telescopes are presented. Recently, a magnet and dual target system have been installed, which allow (n, p) measurements down to 0°. Spectra have been measured for 12C, 13C, 14C, and 90Zr(n,p) for 0°–40° at 65 MeV. The 90Zr data confirm the recently discovered isovector monopole resonance and provide evidence for two new isovector giant resonances: the spin monopole and the isospin T + 1 component of the quadrupole.
