摘 要
我們使用投射殼模型(Projected Shell Model)對Eu的同位素做原子核超形變的理論研究，包括143Eu、147Eu(1)、147Eu(2)、147Eu(3)、147Eu(4)、147Eu(5)等數個偶奇核(偶中子數、奇質子數)。計算Eu的同位素的躍遷能量Eγ、運動學轉動慣量J(1) 和動力學轉動慣量J(2) ，與實驗值作比較從其中瞭解原子核的基本特性及結構。結果我們發現Eu偶奇核中未確定的自旋角動量Ｉ平移數個 ，則實驗值與理論值的數據兩者非常吻合。理論值中發現147Eu具有形狀共存的現象。

Abstract
We apply PSM(projected shell model) to superdeformed phenomena in the Eu isotopes, 143Eu ~ 147Eu odd mass included. In calculating kinetic moment of inertia J(1) and dynamic moment of inertia J(2), comparing with experimental values, we realize the basic property and structure of the nuclear. As a result, we find that the uncertain spin I in 143Eu shifts several . Therefore, the experimental values quite correspond to the theoretical values. In theory, we find there are different superdeformed phenomena in 147Eu.
