利用５５Ｍｎ（３０Ｓｉ，２ｐ２ｎ）反应布居了８１Ｒｂ的高自旋态，ＧＡＳＰ阵列配以由４０个ΔＥ－ＥＳｉ（Ａｕ）望远镜单元所组成的４π带电粒子球进行γγγ带电粒子（质子和α）的符合测量；实验发现了由７条级联γ跃迁所组成的８１Ｒｂ高自旋超形变转动带。其动力学惯量为Ｊ（２）＝４／ΔＥγ＝２６．７（ｈ２／ＭｅＶ），该带被解释为具有四极形变参数β２＝０．５１以及高Ｎ侵入组态为π５１ｖ５２。
The high-spin states of 81Rb were populated with 55Mn (30Si, 2p2n) reactions and the GASP array was fitted with 4π charged particle spheres consisting of 40 ΔE-ESi (Au) telescope units for coincidence measurement of γγγ charged particles (protons and α) The 81Rb high spin superdeformed rotational band composed of seven cascaded γ transitions was found. The kinetic inertia is J (2) = 4 / ΔEγ = 26.7 (h2 / MeV), which is interpreted as having a quadrupole deformation parameter β2 = 0.51 and a high N intrusion configuration of π51v52.
