标题： Existance of octupole correlation in 116Sn

摘要： 负宇称态在116Sn中通过八极相关性进行了研究。 同样使用印度国家伽马阵列（INGA）设施在可变能量回旋加速器中心，科钦，利用反应114Cd({\alpha },2n) 116Sn在34 MeV能量下进行探测。 报道了三种与当前研究相关的新的{\gamma }转变，并根据DCO比率和极化测量确定了相关能级的自旋-宇称。 正宇称基带与负宇称带之间的带间转变被首次观察到，相应的跃迁概率比值B(E1)/B(E2)表明这些核中存在八极相关性。 这些相反宇称带之间E1和E3跃迁的增强跃迁速率以及软八极形变的证实最终有助于该同位素中八极激发的开始。 显示英文摘要

摘要： The negative parity states in 116Sn have been investigated in terms of octupole correlation. The same is probed by using the Indian National Gamma Array (INGA) facility at Variable Energy Cyclotron Centre, Kolkata using the reaction, 114Cd({\alpha},2n) 116Sn at 34 MeV energy. Three new {\gamma}-transitions relevant to the present investigation are reported and the spin-parities of the associated levels are assigned based on the DCO-ratios and polarisation measurements. The interband transitions between the positive parity ground band and the negative parity band are newly observed and the corresponding extracted ratio of transition probability, B(E1)/B(E2) indicated the existence of octupole correlation in these nuclei. The enhanced transition rates for E1 and E3 transitions between these opposite parity bands and corroboration of soft octupole deformation ultimately aid the onset of octupole excitation in this isotope.
