AI 中文摘要
无中微子双贝塔衰变（DBD）和逆贝塔衰变（IBD）的核矩阵元（NMEs）对于利用DBD和IBD研究标准模型之外及之内的中微子性质至关重要。电荷交换核反应（CER）是实验上研究这些NMEs的现实探针。本工作首次展示了一种实验方法，通过明确考虑中心力和张量力相互作用，从CER截面的q（动量转移）依赖性中提取与DBD和IBD相关的伽莫夫-泰勒（GT）和张量（T）NMEs。该方法被应用于用于太阳中微子和镓异常的71Ga上的CER，以及用于DBD和IBD的100Mo和128Te上的CER。讨论了具有张量相互作用的CER对DBD和IBD NME研究的影响。
英文摘要
Nuclear matrix elements (NMEs) for neutrinoless beta-beta decays (DBD) and inverse-beta decays (IBD) are crucial for studying neutrino properties beyond and within the standard model by using DBDs and IBDs. The charge exchange nuclear reaction (CER) is a realistic probe for studying experimentally these NMEs. The present work shows for the first time an experimental way to extract the Gamow-Teller (GT) and tensor (T) NMEs associated with DBDs and IBDs from the q (momentum transfer) dependence of the CER cross-section by taking into accounts explicitly both the central and tensor interactions. The present method was applied for CERs on 71Ga used for the solar-neutrino and the Ga anomaly and on 100Mo and 128Te used for DBD and IBD. Impacts of the CER with the tensor interaction on the DBD and IBD NME studies are discussed.
