原子核

Radioactive series: Any of four sets of unstable heavy atomic nuclei that undergo a series of alpha decay and beta decay until a stable nucleus is achieved.

放射性系：四组不稳定的重原子核，通过一系列α衰变和β衰变直至达到稳定的核为止。

Suddenly there's an alpha particle coming out of it, except the alpha particle is another universe.

The SucceSs of Rutherford's theory of alpha particle scattering giveshim the distinction of having discovered the atomic nucleus.

由于卢瑟福成功地提出了Ot粒子散射理论，人们将发现原子核的荣誉归功于他。

Some nuclei, especially heavier ones, are unstable , or radioactive, emitting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

Some nuclei, especially heavier ones, are unstable, or radioactive, emit ting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

On these basic, we explore the single-particle resonant states by the analytic continuation in the coupling constant method within the framework of the relativistic mean field theory.

在这些工作的基础上，我们将ACCC方法和RMF理论相结合，研究了原子核的单粒子共振态能量、宽度。

Electron has an intrinsic angular momentum in addition to the orbital angular momentum due its motion about the nucleus .

With more mass than the Sun and the density of an atomic nucleus, the spinning pulsar is the collapsed core of a massive star that exploded, while the nebula is the expanding remnant of the star's outer layers.

中心的脉冲星是由大质量恒星塌缩形成的，它的质量比太阳要大而密度和原子核差不多，而星云则是由恒星外层膨胀所形成的。

Occurs at a separation of 1.14a0 between the nucleus at the center and nuclei at the apexes. Therefore the binding energy of 0.5202 a.u. for this structure has been got.

结果表明，当中心原子核与四个顶角原子核间距离为1.14a_0时，体系能量有一极小值-13.9106a.u。，从而得到其结合能为

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
