4) proton emission
质子发射
1.
It is introduced that the proton emission from a spherical nucleus can be well described by WKB method, while that from a deformed nucleus must be described by means of solving coupled channel Schrdinger equations.
球形核的质子发射用 WKB方法可以很好地描述 ,变形核的质子发射则须解耦合道的薛定谔方程 。
5) β-delayed proton decay
β缓发质子衰变
1.
Itsβ-delayed proton decay was studied by means of "p-γ" coincidence in combination with a He-jet tape transport system, including half-lives, proton energy spectra,γ-transitions following the proton emissions, and the branching ratios to the low-lying states in the grand-daughter nuclei.
利用40Ca+96Ru融合蒸发反应产生了近质子滴线核133Sm,配合氦喷嘴带传输系统采用“质子-γ”符合方法观测了它们的β缓发质子衰变,其中包括半衰期、质子能谱、第二代子核低位态之间的γ跃迁,并估计出衰变到第二代子核不同低位态的分支比。

补充资料:“质子-电子偶极-偶极”质子弛豫增强
“质子-电子偶极-偶极”质子弛豫增强
物理学术语。原子核外层中不成对的电子质量小,但磁动性很强,可使局部磁场波动增强,促使氢质子弛豫加快,从而使T1和T2缩短,这种效应即为PEDDPRE。过渡元素和镧系元素大部分在d和f轨道有多个不成对电子,所以其离子往往具有PEDDPRE,可用来作顺磁性对比剂,如钆(Gd)。Gd在外层有7个不成对电子,具有很强的顺磁性。
