$\Delta\epsilon > 0.69$. The particular value of $\bar{a}_0=0.3$ does not permit a CIR at all and is hence monotonically increasing, while departing from $\epsilon=0$ with a finite, non-vanishing slope.

![(Color online) (a) $T_{0}^{(1)}$ versus the scaled energy ${\epsilon}$ for four open channels. Different curves correspond to different values of the short range parameter $C_{10}$. It is clearly observed that the CIR saturates at the confinement induced unitarity bound depicted as the dot-dashed curve. As for general $\ell$ a CIR associated with a transmission blockade is only happening for ${\epsilon}\le 1$. In (b) the transmission coefficient $T_{1}^{(1)}$, when incident in the first excited channel is shown.[]{data-label="fig:transmission_trend_p"}](figures/figure3.eps){width="45.00000%"}

Finally we note that the transmission coefficient goes up to unity at the channel thresholds regardless of the value of the scattering length. Considering the case $\ell=1$, presented in Fig. \[fig:transmission\_trend\_p\], we use the $C_{10}$ parameter to label the different curves. This is due to the narrow width of the $p$-wave free space resonances which makes an energy independent treatment of the scaled $p$-wave scattering length impossible. For each curve the $C_{10}$ parameter is adjusted such that a free-space resonance occurs for every energetic interval $i-1 \le\epsilon\le
i$ for $0\le i\le 4$. Again, at a
