We report on the measurement and analysis of photoionisation, mass-analysed-threshold-ionisation and pulsed-field-ionisation zero-kinetic-energy photoelectron spectra of HD in the vicinity of the dissociative-ionisation thresholds H$^+$ + D(1s) + e$^-$ and H(1s) + D$^+$ + e$^-$.光谱是通过$ v = 11 $ -13的$ \ bar {\ rm h} $和$ \ bar {\ rm b} $ h $ \ bar {\ rm h} $〜$〜$^$^$^$^1σ_g^+$和B $^$ prime^$^$^$^$^$^$^$^1状态并提供有关X $^+$ $^2σ_g^+$ hd $^+$的弱界水平的信息，带有振动量子数量$ v^+= 16 $ -21和旋转的角度 - 动物量子量$ n^+= 0 $ -10。该光谱还揭示了H $^+$+D（1S）解离极限上方的HD $^+$的首次形状和Feshbach共振。 $ \ bar {\ rm h} $和$ \ bar {\ rm b} $状态的结构和解离动力，x $^+$ $ $ $ $^2σ_g^+$和a $^+$^+$^+$^+$^+$^+$^2σ_U^+$^+$^+$ a的ub-mass受核定的影响，受到了核的影响。不对称。
We report on the measurement and analysis of photoionisation, mass-analysed-threshold-ionisation and pulsed-field-ionisation zero-kinetic-energy photoelectron spectra of HD in the vicinity of the dissociative-ionisation thresholds H$^+$ + D(1s) + e$^-$ and H(1s) + D$^+$ + e$^-$. The spectra were recorded via the $v=11$-13 vibrational levels of the $\bar{\rm H}$ and $\bar{\rm B}$ outer wells of the H$\bar{\rm H}$~$^1Σ_g^+$ and B$^{\prime\prime}\bar{\rm B}$~$^1Σ_u^+$ states and provide information on the weakly bound levels of the X$^+$ $^2Σ_g^+$ ground state of HD$^+$ with vibrational quantum numbers $v^+=16$-21 and rotational angular-momentum quantum numbers $N^+=0$-10. The spectra also reveal for the first time shape and Feshbach resonances of HD$^+$ located energetically above the H$^+$ + D(1s) dissociation limit. The structure and dissociation dynamics of the $\bar{\rm H}$ and $\bar{\rm B}$ states of HD and of the X$^+$ $^2Σ_g^+$ and A$^+$ $^2Σ_u^+$ states of HD$^+$ near the dissociation thresholds are strongly influenced by the g/u-symmetry breaking caused by the nuclear-mass asymmetry.
