In this work, the higher-order interactions required in describing triaxial deformation in the interacting boson model are introduced to improve the fitting results to low-lying level energies, B(E2) values and electric quadrupole moments of even\u2013even nuclei. As an example of the model application, the low-lying excitation spectra and the electromagnetic transitional properties of even\u2013even 176\u2212198Pt are fitted and compared to the experimental data and the results of the consistent-Q formalism. It is shown that the results obtained from the model are better than those of the original consistent-Q formalism, indicating the importance of the higher-order interactions in describing the structure and the shape phase evolution of these nuclei.<\/jats:p>","DOI":"10.3390\/sym14122610","type":"journal-article","created":{"date-parts":[[2022,12,12]],"date-time":"2022-12-12T03:02:37Z","timestamp":1670814157000},"page":"2610","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Shape Phase Transitions in Even\u2013Even 176\u2013198Pt: Higher-Order Interactions in the Interacting Boson Model"],"prefix":"10.3390","volume":"14","author":[{"given":"Dongkang","family":"Li","sequence":"first","affiliation":[{"name":"College of Physics, Tonghua Normal University, Tonghua 134000, China"}]},{"given":"Tao","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Physics, Tonghua Normal University, Tonghua 134000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5118-1719","authenticated-orcid":false,"given":"Feng","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Physics, Liaoning Normal University, Dalian 116029, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1069","DOI":"10.1103\/PhysRevLett.35.1069","article-title":"Collectiven nuclear states as representations of a SU(6) group","volume":"35","author":"Arima","year":"1975","journal-title":"Phys.
