Nuclear Rotation and Mechanism of Excitational mode associated with the motion.

为了分析在高K波段（如K = 8^+ in^ Os）观测到的光谱异常行为<182>，我们利用该项目首席研究员提出的摆动运动理论，研究了与旋转运动相关的激发机制。作为能带的一个异常特征，可以指出，由于带头的自旋等于8，所以偶数自旋态是与观测数据收缩的有利态。在比后弯区自旋态稍高的自旋态中，可以肯定地看到特征反转，其中有利的自旋态是高能量的。换句话说，签名反转仅发生在频带交叉点处。从这些事实表明，s带强烈的相互作用与高K带。因此，三带交叉的物理特征是对这一现象最合理的解释，我们认为摆动运动理论是分析这一现象最合适的方法。本文应用母坐标法研究了以倾斜角为母坐标的摆动运动。Hill-Wheeler方程采用角向非投影波函数，由于不稳定性而不能正确求解。内禀波函数被投射到一个确定的角动量态上。通过角动量投影，方程的解更加稳定。我们得到了比较合理的结果，并与实验谱进行了比较。

In order to analyze an abnormal behavior of spectrum observed in high K band like K = 8^+ in^<182>Os, we study the exication mechanism associated with the rotational motion, using theory of wobbling motion, proposed by the head investigator of this project. It may be pointed out as an abnormal feature of the band that, since the spin of the band head is equal to 8, the even spin states are favored states in contraction to the observed data. In a little higher spin states than those in the back bending region, the signature inversion, in which the favored spin states are high in energy, is certainly recognized. In other words the signature inversion takes place at just the band crossing point. From these fact it is suggested that, the s-band strongly interacts with the high-K band. Consequently, the physical feature of 3-band crossing is most reasonable interpretation of the phenomena.We considered that the theory of wobbling motion is most suitable approach to analyze the phenomena mentioned above. The generator coordinate method is applied to studied the wobbling motion in which the tilt angle is employed as a generator coordinate. Hill-Wheeler equation using angular unprojected wave function, is not properly solved because of instability. The intrinsic wave function is projected out onto a definite angular momentum state. Solution of the equation is much stabilized through the angular momentum projection. We obtained rather reasonable results which are compared with the experimental spectra.
