Collective properties of neutron-deficient Nd isotopes: Lifetime measurements of the yrast states in ¹³⁶Nd

NUCLEAR REACTIONS ¹²⁴Te(¹⁶O, 4n), E=80 MeV; measured Eγ, Iγ, γγ-coin, half-lives of levels by recoil distance Doppler shift (RDDS) and Doppler-shift attenuation (DSA) methods and analysis by differential decay curve method (DDCM) using ROSPHERE array at the tandem accelerator facility of IFINHH-Bucharest-Magurele. ¹³⁶Nd; deduced levels, J, π, bands, B(E2). Comparison with five-dimensional collective Hamiltonian (5DCH) calculations with D1S Gogny force. Systematics of energies of ground state and γ bands, and other observables in ^{130,132,134,136,138,140}Nd.
