摘要: 通过^５５Ｍｎ（^３０Ｓｉ，αｐｎ）反应布居了^７９Ｋｒ的高自旋态．用ＧＡＳＰ阵列配以由４０个ΔＥ×ＥＳｉ（Ａｕ）望远镜所组成的带电粒子球实现γγγ－带电粒子符合测量．观测到由相对强度为（２．７±０．３）％的８条级联γ跃迁所组成的^７９Ｋｒ高自旋超形变转动带．除了在转动频率ω＞０．９５ＭｅＶ处急剧下降外，该带的动力学转动惯量近乎常数（22ñ²／ＭｅＶ）并被解释为具有四极形变参数β２＝０．５１以及本征侵入组态为π５^０ν５^１． High-spinstates in ⁷⁹Kr were populated via the fusion evaporation reaction ⁵⁵Mn (³⁰Si,αpn)at 130 MeV.Promptγ γγcharged particle coincidences were measured by using the GASP array in conjunction with the ΔE×E Si(Au) charged particle ball.Asuperdeformed band consisting of 8 γray transitions with an intensity of (2.7±0.3)% has been indentified in ⁷⁹Kr.The dynamic moment of inertia for the band is nearly constant at approxately 22ñ²/MeV below arotational frequency of 0.95 MeV...
