用微观粒子振子模型研究44,46,48Ti的极化电荷性质,并用于研究其转晕趋终止带的电四极跃迁。在pf壳模型计算中,通常采用的经验有效电荷值的适用性在这里得到理论上的证实。与44,46,48Ti的实验结果相比,计算的电四极跃迁B(E,I→I-2)和电磁矩能很好地重复出实验结果。发现当接近带终止态时随着价核子集中到1f7/2壳其B(E2)显示出整体的减小。48Ti的I=6+态显示出异常表现且伴有不规则的B(E2)和电磁矩符号的改变,这种现象是由中子主导的长椭球形核形状引起的。
The microscopic particle oscillator model is used to study the polarization charge properties of 44, 46, 48Ti and to study the electrical quadrupole transitions of the dizziness. The applicability of the empirically valid charge values commonly used in the pf shell model calculations is here confirmed theoretically. Compared with the experimental results of 44, 46 and 48Ti, the calculated electric quadrupole transition B (E, I → I-2) and the electromagnetic moment can reproduce the experimental results well. It was found that B (E2) showed an overall decrease with concentration of the valence nucleus to 1f7 / 2 shell when approaching the end-of-band state. The I = 6 + state of 48Ti shows anomalous behavior accompanied by an irregular change in the sign of B (E2) and the moment of the electromagnetic moment caused by the neutron-dominated ellipsoidal nuclear shape.
