【摘要】在兰州放射性束流装置 RIBLL上 ,利用磁刚度 Bρ、飞行时间 t TOF和多重望远镜ΔE- E联合探测方法测量了 69Me V/u36Ar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 2 5P.更多还原

【Abstract】 The mass distribution of the phosphor fragments induced by projectile fragmentation reaction of 69 MeV/u 36 Ar + 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 t TOF and their energy loss Δ E . The experimental isotope distribution was compared to the result of the empirical parameterization EPAX. Three events for the new nuclide 25 P in the region of proton drip line were found in experiment of five days.更多还原
