标题： Effects of nuclear structure on average angular momentum in subbarrier fusion

摘要： 我们研究核四极矩和十六极矩耦合对亚屏障融合反应中平均角动量的影响。 这一量可以作为探测核形状的手段，区分长椭球与短椭球四极矩以及正十六极矩与负十六极矩耦合。 我们描述了氧加钐系统中的数据，并讨论了更重的系统，在这些系统中形状效应更加明显。 显示英文摘要

摘要： We investigate the effects of nuclear quadrupole and hexadecapole couplings on the average angular momentum in sub-barrier fusion reactions. This quantity could provide a probe for nuclear shapes, distinguishing between prolate vs. oblate quadrupole and positive vs. negative hexadecapole couplings. We describe the data in the O + Sm system and discuss heavier systems where shape effects become more pronounced.
