Ab-initio nuclear structure has achieved outstanding results following the introduction of nuclear forces based on chiral EFT and developments in many-body theory. Methods such as Self-Consistent Green's Functions and Coupled Cluster have reached nuclei in the pf-shell. However, these applications have so far been limited to closed-shell isotopes. The present proposal requests travel funds needed to continue an on-going collaboration that addresses this issue. The project is at an advanced stage and its focus (ab-inito calculations for medium-mass open-shells) is of interest to the international theory community. Completing the project will require three trips to the CEA, Saclay, to work with collaborators and a post-doc involved. If its continuation is funded, it is plausible that it will contribute to including the UK to the list of countries active in ab-initio nuclear structure. This may add to the strong reputation in nuclear theory that the University of Surrey already has. The possibility of studying spectral functions of open-shell systems will also offer a solid theoretical support to quasi-free scattering (QSF) and knockout experiments. Several UK groups are active on these issues and there are experiments planned at international institutions such as GSI or RIKEN. Finally, the requested grant would allow me to honour my commitments in the organization of a related workshop at the ESNT of Saclay that has been already approved but for which I miss travel funding.

随着基于手征EFT的核力的引入和多体理论的发展，从头算核结构研究取得了突出的成果。自洽的绿色函数和耦合团簇等方法已经应用到pf壳层的核。然而，这些应用迄今为止仅限于闭壳层同位素。本提案要求提供所需的差旅费，以继续开展解决这一问题的持续合作。该项目处于高级阶段，其重点（中等质量开壳层的ab-inito计算）是国际理论界感兴趣的。完成该项目将需要三次前往CEA，萨克雷，与合作者和博士后参与工作。如果它的继续得到资助，它似乎将有助于将联合王国列入积极参与从头开始核结构的国家名单。这可能会增加萨里大学在核理论方面已经拥有的强大声誉。研究开壳层体系光谱函数的可能性也将为准自由散射（QSF）和敲除实验提供坚实的理论支持。英国的几个团体正在积极研究这些问题，并计划在GSI或RIKEN等国际机构进行实验。最后，所要求的赠款将使我能够履行我在萨克雷的ESNT组织一个相关研讨会的承诺，该研讨会已经获得批准，但我错过了旅行资金。
