Abstract

Molecular resonances having the 6He+6He and 4He+6He structures, which have recently been observed in the highly excited 12Be and 10Be, respectively, are studied by the microscopic coupled-channels (CC) calculation in which excitations of the soft-dipole and quadrupole modes of the colliding 6He nuclei are taken into account in the Goldhaber-Teller model. The CC calculation predicts several molecular-rotational bands in the energy range of the observed resonances and the energies and spins of the calculated resonances agree well with the experimental data.

高激发态12be和10be的分子态
6He+6He和4He+6He结构的分子共振,最近分别在12Be和10Be中观察到,用微观耦合通道(CC)计算进行了研究,其中在Goldhaber-Teller模型中考虑了碰撞6He核的软偶极子和四极子模式的激发。CC计算在观测到的共振能量范围内预测了几个分子旋转带,计算出的共振能量和自旋与实验数据吻合较好。
