Quadrupole deformation of ¹⁶C studied by proton and deuteron inelastic scattering

NUCLEAR REACTIONS ¹H(¹⁶C, p), (¹⁶C, p'), ²H(¹⁶C, d), (¹⁶C, d'), (¹⁶C, nd)¹⁵C, (¹⁶C, 2nd)¹⁴C, , E=24.0 MeV/nucleon, [secondary ¹⁶C beam from ⁹Be(¹⁸O, X), E=59.6 MeV/nucleon using RIBLL facility at IMP-Lanzhou]; measured reaction products, time-of-flight and energy losses of charged particles, (particle)(light particles)-coin, (¹⁶C)(light particle recoils)(θ), differential σ(θ) using E-ΔE telescopes; deduced kinematics for the recoil protons and deuterons from (CH₂)_n and (CD₂)_n targets, Q-value spectra, neutron and proton deformation lengths for the first 2+ state in ¹⁶C, B(E2), ratio of neutron and proton transition matrix element M_n/M_p. Comparison with previous experimental data, and with predictions from two calculations: shell model using MK, WBT, WBT* and YSOX interactions in p-sd model space, and the ab initio in-medium similarity renormalization group (IM-SRG).
