Measurement of enhanced electric dipole transition strengths at high spin in ¹⁰⁰Ru: Possible observation of octupole deformation

NUCLEAR REACTIONS ¹⁰⁰Mo(α, 4n), E=45 MeV; measured reaction products, Eγ, Iγ, γ-γ-coin.; deduced γ-ray energies, level T_1/2 of the high-spin levels of the two alternating-parity bands, B(E2), B(E1), level scheme. Comparison with with the calculated transition rates using the triaxial projected shell model without octupole deformation. The line-shape analyses, the Doppler shift attenuation method, the Indian National Gamma Array (INGA), the K-130 cyclotron at the Variable Energy Cyclotron Centre, Kolkata.
