Study of (d, p) and (d, t) Reaction on theXe136Isotope

Abstract

Eight levels of ${\mathrm{Xe}}^{137}$ and seven of ${\mathrm{Xe}}^{135}$ were observed in the ${\mathrm{Xe}}^{136}(d, p)$ and ${\mathrm{Xe}}^{136}(d, t)$ reactions. The angular distributions of the proton and triton groups were analyzed using zero-range distorted-wave Born-approximation calculations to extract spectroscopic information. Spin and parity assignments for most of the observed states were attempted. Comparison with ($d, p$) and ($d, t$) reaction on ${\mathrm{Ba}}^{138}$, ${\mathrm{Ce}}^{120}$, and ${\mathrm{Nd}}^{142}$ reveals that the multiplicity of the hole states in the $N=81\mathrm{}$ isotones is much lower than that of the particle states in the $N=83\mathrm{}$ isotones.
