本三部曲的第二篇文章介绍了一种名为连续收缩（Continuous Deflation）的新方案，用于在薛定谔集体-内禀模型（SCIM）中构建连续且规则的激发路径，并将其应用于核裂变研究。研究表明，即便结合粒子数投影，使用标准2QP激发也无法一致地应用SCIM框架。鉴于对低能裂变中对破坏的核心作用，我们探索如何构建包含该机制且满足SCIM连续性和正则性态要求的内禀激发态。为此，我们先单独分析通过正交性约束构建激发态的收缩（Deflation）过程，随后沿形变路径引入额外连续性约束以扩展该构建，从而定义出基于激发态生成连续路径的连续收缩方法。特别地，我们在240Pu的绝热和非对称裂变路径基础上构建了10条此类连续路径，并系统分析所得激发态的微观结构；之后研究了断点附近的多种碎片性质，包括中子与质子化学势、中子颈缩以及碎片粒子数分布，并将其与绝热对应物进行比较。
英文摘要
This second article of the trilogy presents the implementation of a third protocol, referred to as Continuous Deflation, designed to construct continuous and regular excited paths within the Schrodinger Collective-Intrinsic Model (SCIM), with applications to nuclear fission. We show that the use of standard 2QP excitations, even when combined with particle-number projection, prevents a consistent application of the SCIM framework. Motivated by the central role of pair breaking in low-energy fission, we explore how to construct intrinsic excited states that incorporate this mechanism while satisfying the continuity and regularity state requirements of the SCIM. To this end, we first analyze the Deflation procedure alone, which constructs excited states through orthogonality constraints. We then extend this construction along a deformation path by introducing an additional continuity constraint, thereby defining the Continuous Deflation method, which generates continuous paths based on excited states. In particular, we construct ten such continuous paths built on top of the adiabatic and asymmetric fission path of 240Pu. The resulting excited states are systematically analyzed in terms of their microscopic structure. We then investigate several fragment properties near scission, including neutron and proton chemical potentials, neutron necking as well as fragment particle-number distributions, and compare them with their adiabatic counterparts.
