摘要

采用pf (I)和fpg9/2 （II）两个模型空间和各种有效相互作用，对富中子偶钛同位素进行了大规模壳层模型计算。得到了能量谱和电磁量，并与已有的实验数据进行了比较。21+态的激发能和B（E2）值的理论结果证实了在N = 32处存在亚壳闭合，而在N = 34处不存在亚壳闭合。此外，还对没有实验数据的激发态的B（E2）和B（M1）值进行了预测。这些预测可作为未来实验比较的有价值参考。

Study of nuclear structure properties of some neutron-rich even-even Titanium isotopes

The large-scale shell-model calculations have been performed for neutron-rich even-even titanium isotopes by employing two model spaces: pf (I) and fpg_9/2 (II) and various effective interactions. The energy spectra and electromagnetic quantities have been obtained and compared with the available experimental data. The theoretical results on excitation energies and B(E2) values of

state confirm the existence of subshell closure at N = 32 and the absence of subshell closure at N = 34. Besides, the B(E2) and B(M1) values of excited states are also predicted for which experimental data are not available. These predictions may serve as a valuable reference for future experimental comparisons.
