Description
In $[1]$ we have investigated the cross sections of the $^{13}C(d,p \gamma)^{14}C(3^–$; 6.73 MeV) reaction at $E_d$ = 15.3 MeV. In this article the double-differential cross sections of the same reaction were measured for six proton emission angles on the SINP MSU 120-cm cyclotron. The angular correlation functions $W(θ_\gamma, \varphi_\gamma; θ_p)$ were measured at four planes of gamma-rays registration. It allowed to restore sixteen even $A_{k \kappa}(θ_p)$ components of density matrix spin-tensor of the final nucleus $^{14}C(3^–)$. The obtained $A_{k \kappa}(θ_p)$ were used to determine other $^{14}C(3^–)$ orientation characteristics: the populations $P(θ_p)$ of sublevels with the M projection of the $3^-$ spin, orientation tensors $t_{k \kappa}(θ_p)$ and polarization tensors $T_{k \kappa} (2 \leq k\leq 6)$.
Experimental data were compared with theoretical ones, obtained within the neutron stripping mechanism by the coupled-channel method (code FRESCO [2], dotted curves in fig. 1a, b, c) and for the compound nucleus statistical mechanism (code CNCOR [3], dash-dot curves).
Our model analysis of $^{14}C(3^–)$ orientation characteristics has revealed that neutron stripping mechanism are dominant mechanisms of $^{13}C(d,p )^{14}C(3^–)$ reaction.
