abstract = {In this article, we derived conditions on the order    ν of the classical Bessel functions        J          ν       that guarantee the inclusion of three distinct normalized forms of        J          ν       in a subclass of    α-spirallike functions. The primary goal was to determine the subintervals within    (  −      π    2    ,      π    2    ) where these inclusion conditions are satisfied. A key component in establishing our results was the upper bound of the ratio        J          ν      +      1        (  1  )      /        J          ν        (  1  ). The theoretical findings were validated through numerical experiments and accompanying graphical demonstrations.}
