我们测量了富中子p-sd和sd壳层区的中子分离能（S（n））和相互作用截面（σ（I））。最近，两个测量都达到了中子滴线，或者接近滴线，对于Z =3的核，这表明一个新的幻数的产生。σ（I）的中子数依赖性显示，当N = 15时，σ（I）大幅增加，这支持了新的幻数。本文还讨论了新幻数的起源。
We have surveyed the neutron separation energies (S(n)) and the interaction cross sections (sigma(I)) for the neutron-rich p-sd and the sd shell region. Very recently, both measurements reached up to the neutron drip line, or close to the drip line, for nuclei of Z/=3), which shows the creation of a new magic number. A neutron-number dependence of sigma(I) shows a large increase of sigma(I) for N = 15, which supports the new magic number. The origin of the new magic number is also discussed.
