Pseudo SU(4) symmetry in nuclei
✍ P. Van Isacker; O. Juillet 📂 Article 📅 1999 🏛 Elsevier Science 🌐 English ⚖ 202 KB

As an alternative to Wigner's spin-isospin symmetry, known to be broken in heavier nuclei, a pseudo SU(4) symmetry is proposed which follows from the combined invarianee in pseudo spin and isospin. Its consequences with regard to Gamow-Teller fl decay are pointed out.
