摘要

We present the complete set of measured inelastic angular distributions (ADs) for d $+^{9}$ $+^{9}$ Be system at a deuteron beam energy ( $E_\textrm{d}$ $E_{d}$ ) of 14.5 MeV, corresponding to the ( $\frac{1}{2}^+$ ${\frac{1}{2}}^{+}$ , $E_x=$ $E_{x} =$ 1.684 MeV) and ( $\frac{5}{2}^+$ ${\frac{5}{2}}^{+}$ , $E_x =$ $E_{x} =$ 3.049 MeV) excited states of ⁹Be. These measured inelastic ⁹Be(d,d)⁹Be* ADs, along with the previously measured ⁹Be(d,d)⁹Be elastic ADs at $E_\textrm{d }=$ $E_{d} =$ 7–35 MeV, were analysed in various nuclear potentials. The inelastic AD data for the studied ⁹Be excited states were modelled within the coupled-channel (CC) framework and the corresponding deformation parameters were extracted. Additionally, we present the measured ADs for the ⁹Be(d,t)⁹Be neutron pickup transfer reaction at $E_\textrm{d }=$ $E_{d} =$ 14.5 MeV, populating the (0 $^+$ $^{+}$ , $E_x =$ $E_{x} =$ 0.0 MeV) and (2 $^+$ $^{+}$ , $E_x =$ $E_{x} =$ 3.04 MeV) states of $^{9}$ $^{9}$ Be. The $^{9}\hbox {Be(d,t)}^{9}$ $^{9} {Be(d,t)}^{9}$ Be transfer reaction was analysed using the method of distorted waves Born approximation (DWBA) and the optimal spectroscopic amplitudes (SAs) of the configurations $^{9}$ $^{9}$ Be $\rightarrow ^{9}$ $\to^{9}$ Be + n and $^{9}$ $^{9}$ Be $\rightarrow ^{9}$ $\to^{9}$ Be* $+ $ $+$ n were determined and cross-checked with the existing literature values.
