The energies, magnetic dipole and electric quadrupole moments, spectroscopic factors of the ground and excited states of 109Ag and 107Ag, the reduced probabilities of electromagnetic transitions between them, and the reduced probabilities of β transitions
from the ground states of 109Cd and 107Cd to the excited states of 109Ag and 107Ag were calculated on the basis of the dynamic collective model. The vacuum fluctuations of quasiparticles and multiphonon
(up to 10 phonons) states of the main band of the even-even core were taken into account. The calculation results show good
agreement with the experimental data. 相似文献

本文把用于处理重离子引起的单粒子转移反应的Goldfarb-Buttle方法推广到多粒子转移反应。计算了12C(7Li,t)16O和20Ne(d,6Li)16O反应,用了16O的全相干波函数,考虑了某些反冲因素,并将结果与实验作了比较。 相似文献

利用能量为170MeV左右的36Ar重离子束轰击96Ru和106Cd浓缩同位素靶,分别生成缺中子同位素130Nd和140Tb.借助氦喷嘴带传输系统,用X–γ和γ–γ符合方法,分离鉴别了这两种核素,并进一步测定了它们的衰变性质.得到130Nd的半衰期为(13±3)s,首次建议了它的EC/β+衰变纲图,推测了其子核130Pr的基态和低位能级的自旋宇称.修订了140Tb的原有极简单的EC/β+衰变纲图并指认140Tb的基态自旋宇称为7+. 相似文献

In this study,218Ac and 221Th nuclides were produced via the heavy-ion induced fusion evaporation reaction 40Ar+186W.Their decay properties were studied with the help of the gas-filled recoil spectrometer SHANS and a digital data acquisition system.The cross section ratio between 222Pa and 218Ac was extracted experimentally,withmeasured value 0.69(9).Two new possible α decay branches to 221Th are suggested.The valence neutron configurations for the daughter 217Ra are discussed in terms of the hindrance factors. 相似文献

假定11Li,14Be和17B是由N=2Z核芯和两个外层中子组成的三体系统,核芯-中子和中子-中子间的作用为弱吸引指数势,不足以形成核芯-中子和中子-中子二体束缚态.本文的计算表明,核芯-中子-中子三体系统可形成束缚态,计算结果基本上解释了11Li,14Be,17B的基态能量和异常大核半径的实验结果. 相似文献
