Evolution of the one-phonon 2_{1, ms} mixed-symmetry state in N=80 isotones as a local measure for the proton-neutron quadrupole interaction

NUCLEAR REACTIONS ¹²C(¹³⁴Xe, ¹³⁴Xe'), E=435 MeV; measured Eγ, Iγ, γγ-coin using DSA technique and the Gammasphere array. ¹³⁴Xe; deduced levels, J, π, δ, B(E2), B(M1), related properties. Systematics of N=80, 82 isotones discussed.
