Experimental study of excited states of ⁶²Ni via one-neutron (d, p) transfer up to the neutron-separation threshold and characteristics of the pygmy dipole resonance states

NUCLEAR REACTIONS ⁶¹Ni(d, p), E=16 MeV; measured Ep, Ip, σ(θ) using Super-Enge Split-Pole Spectrograph (SE-SPS) at the Superconducting Linear Accelerator and Super-FN Tandem van-de-Graaff accelerator facilities of Florida State University. ⁶²Ni; deduced levels, L-transfers J, π, configurations, spectroscopic factors, total cross sections. Adiabatic distorted wave approximation (ADWA) analysis using the coupled-channels program CHUCK3 for analysis of angular distributions. Comparison with previous experimental results in the ENSDF database. ⁶²Ni(γ, γ'), E not given; measured Eγ, Iγ, γγ(θ); deduced partial results of the experiment for pygmy dipole resonances (PDR) shown in Fig. 8d of the paper, while detailed results to be published elsewhere.
