报告题目:Isovector and isoscalar pairing in low-lying states of atomic nuclei
摘要:The pair correlation is very important in nuclear physics. Isovector nucleon pairs with spin J = 0 are found to be dominant ingredients in low-lying states of semimagic nuclei. The isovector J = 0 pair correlation plays a key role in nuclear infinite matter. These facts are the consequences of the strong isovector J = 0 pairing interaction between nucleons. On the other hand, Isoscalar J = 1 and J = 2j (for a large-j orbit) pairing interactions are strong. Therefore the isoscalar deuton-like J = 1 pair correlation and isoscalar spin-aligned J = 2j pair correlation may be very important in low-lying states of N = Z nuclei. The question is whether or not a pair correlated state (or a pair-condensation state) can be formed. In this talk, I will show our study on pair correlations in low-lying states of atomic nuclei. The isoscalar J = 1 and 2j, as well as isovector J = 0, pair correlations will be discussed for both even-even and odd-odd nuclei.
