These efforts are motivated by the continual observation of unexpected structure phenomena in nuclei with unusual proton-to-neutron ratios. In recent decades, laser spectroscopy techniques have made significant contributions in our understanding of exotic nuclei in different mass regions encompassing almost the entire nuclear chart. This is achieved through determining multiple fundamental properties of nuclear ground and isomeric states, such as nuclear spins, magnetic dipole and electric </span>quadrupole<span><span> moments and charge radii, via the measurement of hyperfine structures<span> and isotope shifts<span> in the atomic or ionic spectra of the nuclei of interest. These properties offer prominent tests of recently developed state-of-the-art nuclear theory and help to stimulate new developments in improving the many-body methods and nucleon–nucleon interactions at the core of these models. With the aim of exploring more exotic short-lived nuclei located ever closer to the proton and neutron driplines, laser spectroscopy techniques, with their continuous technological developments towards higher resolution and higher sensitivity, are extensively employed at current- and next-generation radioactive ion beam facilities worldwide. Ongoing efforts in parallel promise to improve the availability of these even more exotic species at next-generation facilities. Very recently, an innovative application of laser spectroscopy on molecules containing short-lived nuclei has been demonstrated offering additional opportunities for several fields of research, e.g. fundamental symmetry studies and astrophysics. In this review, the basic nuclear properties measurable with laser spectroscopy will be introduced. How these observables are associated with </span></span></span>nuclear structure and nucleon–nucleon interactions will be discussed. Following this, a general overview of different laser spectroscopy methods will be given with particular emphasis on technical advancements reported in recent years. The main focus of this article is to review the numerous highlights that have resulted from studying exotic nuclei in different mass regions with laser spectroscopy techniques since the last edition in this series.

A brief survey of the experimental techniques and recent experimental findings is presented as an introduction to the main part of the paper. The presence of the PDR on stable and unstable nuclei with neutron excess is well established in theoretical and experimental studies. The theoretical approaches are reviewed starting from the macroscopic collective models to the microscopic mean-field theories. The isospin mixed nature of the PDR – reproduced by all the microscopic approaches – allows to study the excitation with isovector and isoscalar probes. To draw a better picture on the structure of this mode is therefore important to complement the theoretical studies with detailed investigation on the reaction mechanism. To this mean, this paper gives specific focus to the description of the cross section calculations. The semiclassical Coupled Channel equations are shortly reviewed with particular attention to the construction of the nuclear potential and radial form factors with the microscopic transition densities. The interplay of Coulomb and nuclear contributions, their dependence on mass, charge and incident energy are analysed with the help of few selected examples. Most of the features of the PDR are well described by the theoretical approaches even though few open question remain to be clarified. Among them a discussion on the collectivity of the mode, isospin splitting and role of deformation is presented. Most of the theoretical works and the new experimental findings on the collective properties of the PDR jeopardise the common picture of this excitation mode as related to the oscillation of the neutron skin against an inert core The question on the influence of the neutron excess on other multipolarities is also reviewed.</p></div>","PeriodicalId":412,"journal":{"name":"Progress in Particle and Nuclear Physics","volume":null,"pages":null},"PeriodicalIF":9.6,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2703852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
