Transition probability, B(E2)↑, from the ground to the first-excited 2+ state of even-even nuclides

Abstract

Adopted values for the reduced electric quadrupole transition probability, B(E2)↑, from the ground state to the first-excited 2+ state of even-even nuclides are given in Table I. Values of τ, the mean life of the 2+ state, E, the energy, and β2, the quadrupole deformation parameter, are also listed there. The ratio of β2 to the value expected from the single-particle model presented. The intrinsic quadrupole moment, Q0, is deduced from the B(E2)↑ value. The product E × B(E2)↑ is expressed as a percentage of the energy-weighted total and isoscalar E2 sum-rule strengths. Table II presents the data on which Table I is based, namely the experimental results for B(E2)↑ values with quoted uncertainties. Information is also given on the quantity measured and the method employed. The literature has been covered to January 1986. © 1987.
