Fractional Parentage Coefficients for Composite Pairs

Abstract

A new set of fractional parentage coefficients is introduced to build the orthogonal basis of states with many and pairs in the microscopic theory of low-lying collective motion in nuclei.

Shape Coexistence in Odd-Mass Nuclei near Z = 50

“…becomes strong. Therefore, besides the n-p quadrupole-quadrupole interaction used in this work, the Heisenberg part of the n-p effective interactions may need to be included in the HamiltonianJ 13 ' Since the part is missing from this work, we use a too large value of the parameter K VV to bring the A J = 1 I59/2 intruder bands to come down. And moreover, the calculated intruder bands are a little higher compared with the experiment.…”

Pair Excitations in Even-Even Nuclei

“…In Ref. [6] several forms of effective interactions are proposed and discussed. In our previous work on doubly even-' 8 ' 9 ' and odd-mass' 10 !…”

Charge Exchange Component of n-p Interactions

“…Parameters used in the calculations. Except those explicitly specified, all values are in unit of [(mut/h)2 MeV].G Z…”
