| 英文摘要 | We introduce the formalism to describe heavy-ion double-charge-exchange (DCE) processes in the eikonal approximation. We focus on the low-momentum-transfer limit, corresponding to the differential cross section at theta = 0 degrees, and for the first time, we show that it is possible to factorize the DCE cross section in terms of reaction and nuclear parts. Whereas in the theta not equal 0 degrees case the nuclear part is a convolution of the beam and target nuclear matrix elements (NMEs), for theta = 0 degrees we demonstrate for the first time that the transition matrix elements can be written as the sum of double Gamow-Teller (DGT) and double Fermi (DF) type parts, and that they can both be further factorized in terms of target and projectile NMEs. By making use of the interacting boson model (IBM) formalism, we also show that the DGT and total parts of the neutrinoless double-beta-decay NMEs are in linear correlation with DCE-DGT NMEs. This confirms the hypothesis of a linear correlation between them, as introduced earlier [N. Shimizu et al., Phys. Rev. Lett. 120, 142502 (2018)]. The possibility of a two-step factorization (TSF) of the very forward differential DCE cross section and the emergence of DGT and DF types for the DCE nuclear matrix elements, combined with a linear correlation between DCE-DGT and 0 nu beta beta NMEs, opens the possibility of placing an upper limit on neutrinoless double-beta-decay NMEs in terms of the DCE experimental data at theta = 0 degrees. |
