Chapter 12: Q11P (page 598)

From (17.4), show that, $h_{n}^{(1)} (ix) = - e^{- x} / x$ .

Short Answer

Expert verified

The figures show the behavior of Bessel functions of different kinds.

Step by step solution

Concept of Spherical Bessel functions:

Spherical Bessel function is given as follows:

$h_{n}^{(1)} (x) = j_{n} (x) + {iy}_{n} (x)$

With:

$j_{n} (x) + x^{n} {(- \frac{1}{x} \frac{d}{dx})}^{n} (\frac{\sin (x)}{x}) y_{n} (x) = - x^{n} {(- \frac{1}{x} \frac{d}{dx})}^{n} (\frac{\cos (x)}{x}) Formula used : j_{n} (x) = {鈭�}_{r = 0}^{鈭�} \frac{{(- 1)}^{r}}{螕 (r + 1) 螕 (r + 1 + n)} {(\frac{x}{2})}^{2 r + n}$

Calculate the equation by the Spherical Bessel function:

Using the Spherical Bessel function to obtain:

$h_{n}^{(1)} (x) = j_{n} (x) + {iy}_{n} (x) = h_{n}^{(1)} (ix) = j_{n} (ix) + {iy}_{n} (ix) = h_{0}^{(1)} (ix) Simplify further as follows : h_{n}^{(1)} (x) = j_{n} (ix) + {iy}_{0} (ix) = [\frac{\sin ix}{ix} - i \frac{\cos ix}{ix}] = [\frac{\sinh x}{x} - i \frac{\cosh x}{x}] = - \frac{e^{- x}}{x} Hence, h_{0}^{(1)} (ix) = - \frac{e^{- x}}{x} .$
