Query: Hyperspherical few-body model calculation for cascade $\Xi$ exotic
  hypernuclei with reference to nuclear drip lines   In this paper, we presented the ground state energies calculated for some
single and double cascade hyperon(${\Xi}^{-}$) hypernuclei. For hypernuclei of
the type $_{\Xi}^{A_c+1}$X we applied $\Xi+^A_c$X two-body model and for
hypernuclei of the type $_{\Xi\Xi}^{A_c+2}$X we adopted $\Xi+\Xi+^A_c$X
three-body model. A two-term Gaussian (Isle type) potential with adjustable
parameters is chosen as the $\Xi$-nucleus interaction, while a two-term
Yukawa-type potential has been chosen for the $\Xi\Xi$ pair. In the three-body
model calculation, we adopted the hyperspherical harmonics expansion (HHE)
formalism. The resulting two- and three-body Schr{\"o}dinger equations subject
to appropriate boundary condition's have been solved numerically to get the
ground-state energies and wavefunctions. Computed values are in excellent
agreement with the observed ones as found in the literature. Analysis of the
calculated observables indicates that the hyperons stay close to the
core-nucleus. Hypernuclei formed as a result of absorption of one or more
$\Xi$-hyperon(s) by a normal nucleus (bound or unbound) are found to have more
stability than those formed as a result of absorption of one or more $\Lambda$
hyperon(s) by the same nucleus. This fact flashes towards the possibility of
the existence of a valley of strange hypernuclei near the drip lines.
