磁转动物理的提出是原子核转动研究中继回 弯现象、超形变转动带、之后的又一重大成果. 与通常的高自旋态和超形变转动带不同，磁转动带 通常发生在近球形或弱形变原子核中. 在磁转动带 中，是磁偶极矩在转动，而非通常的电四极矩转动. 磁偶极矩来源于少数质子-粒子（或空穴）和中子-空 穴（或粒子）之间的耦合，并且绕总角动量转动. 在转动带带首，质子、中子角动量近乎 垂直，两者耦合的结果使总角动量矢量倾斜于原子 核的惯性主轴. 由于系统的形变很小，要获得角动 量，最可能的结果是质子和中子的角动量互相靠 拢，而总角动量的方向变化不大，从而可以形成规 则的转动谱. 由于质子和中子角动量就象一把正在 合拢的剪刀，因此形象地称之为“剪刀带”. 然而不 同于在形变核中由集体转动形成的正常转动带，这 种剪刀带通常存在于近球形或弱形变的原子核中. 区别于正常的转动带（称为电转动），从物理角度 上，它又被称为磁转动带. 实验上，磁转动带首次 在199Pd 中得以证实.目前，已先后在100 区、 130 区、和200区发现了磁转动现 象. |

Physical magnetic rotation of the proposal is to turn the relay nuclei backbending phenomenon superdeformed rotational band, followed by another major achievement. With the usual high-spin states and superdeformed rotational band is different from magnetic rotational band usually occurs in nearly spherical or weakly deformed nucleus. the magnetic rotational band, is the magnetic dipole moment in the rotation, rather than the usual electric quadrupole rotation. magnetic dipole moment comes from a small number of protons - particles (or holes) and neutron - hole (or particles) between the coupling and the rotation around the total angular momentum. In the first rotational band, proton, neutron angular momentum nearly vertical, the result of the coupling between the angular momentum vector inclined to the inertia of the spindle in the nucleus. Since the deformation of the system small, to obtain the angular momentum, the most likely outcome is that the angular momentum of protons and neutrons to move closer to each other, and little change in the direction of total angular momentum, which can form a regular rotational spectra. Since the angular momentum as protons and neutrons a pair of scissors are closed, so vividly described as "scissors with." However, unlike in the rotating deformed nucleus formed by the normal rotation of collective belt, this pair of scissors with commonly found in nearly spherical or weakly deformed nucleus. different from the normal rotational bands (called power rotation), from the physical point of view, it is known as magnetic rotational bands. experiment, the magnetic rotational bands to be confirmed in the first time in 199Pd. At present, it has already in the 100 area, 130 area, and 200 were found the phenomenon of magnetic rotation. 绝对专业 |
