质子滴线区新核素25P的鉴别

  • 摘要: 在兰州放射性束流装置RIBLL上 ,利用磁刚度Bρ、飞行时间tTOF和多重望远镜ΔE- E联合探测方法测量了69Me V/u 36Ar轰击Be靶产生的 P同位素碎片的同位素分布,并与 EPAX经验公式的计算结果进行了比较 ,在质子滴线区首次鉴别出了新核素25PThe mass distribution of the phosphor fragments induced by projectile fragmentation reaction of 69 MeV/u 36Ar + 9Be was measured at the projectile fragment separator RIBLL at IMP. The fragment products were identified by determining the magnetic rigidity Bρ , the time of flight tTOF and their energy loss ΔE . The experimental isotope distribution was compared to the result of the empirical parameterization EPAX. Three events for the new nuclide 25P in the...
