论文摘要
我们在这里报告了一种经验形式主义，用于预测相对论\ b {eta}的碎片化产生的富含中子核的横截面 - 中质质量区域的中子富含中子弹丸。形式主义基于弹丸碎片反应的磨损形式。已经表明，形式主义可以准确地重现132SN碎片中产生的核的实验横截面数据。表明，形式主义还可以重现129xe碎片中富含中子核的实验横截面。形式主义用于在中子富的同位素的生产横截面中带来优势，尤其是中子较丰富的同位素。通过使用不稳定的魔法中子富含弹丸132SN，人们可以期望的是，与中子富含中子的不稳定弹丸128SN和124SN相比，这是SN（TIN）稳定的同位素中最富含中子的同位素。形式主义用于预测在不稳定的144xE和146cs的碎片反应中产生的富含中子核的横截面，预计它们将在即将到来的肋骨设施中以及光束强度升级后现有的肋骨设施中产生足够的强度。
We report here an empirical formalism for predicting the cross-sections of neutron-rich nuclei produced in fragmentation of relativistic \b{eta}-unstable neutron-rich projectiles in the mid-mass region. The formalism is based on the abrasion-ablation picture of the projectile fragmentation reaction. It has been shown that the formalism can accurately reproduce the experimental cross-section data for nuclei produced in the fragmentation of 132Sn. The formalism, it is shown, can also reproduce the experimental cross-sections of neutron-rich nuclei produced in the fragmentation of 129Xe fairly accurately. The formalism is used to bring out the advantage in the production cross-sections of neutron-rich isotopes, especially the more neutron-rich ones; that one can expect by using unstable doubly magic neutron-rich projectile 132Sn as compared to comparatively less neutron-rich unstable projectile 128Sn and also 124Sn, the isotope which is most neutron-rich among the stable isotopes of Sn (tin). The formalism is used to predict the cross-sections of neutron-rich nuclei produced in the fragmentation reaction of unstable 144Xe and 146Cs, which are expected to be produced with sufficient intensity in the upcoming RIB facilities and in the existing RIB facilities after beam intensity upgrade.
