This textual content issues ‘semiclassical’ inside of a number of meanings. those contain the time-honored JWKB approximation and its phase-integral generalizations in bankruptcy 2 to 2 and 4 transition issues without or with one or poles: by way of corollary, crossing and non-crossing nonadiabatic collision thought. Above and under threshold Wannier ionization is roofed in bankruptcy three the place the massive parameters are the inverses of the difference of the hyperspherical angles from their ridge values. The extra frequent influence parameter remedy, within which the potentially relativistic heavy-particle relative movement is handled classically and the electrons quantally, is definitely lined in bankruptcy four. Diffusion in solids and beverages is defined in bankruptcy five the place mostly the massive parameter is the peak of the barrier that's conquer by means of thermal agitation. Hypergeometric capabilities are brought in bankruptcy 1 and Mittag-Leffler features in Appendix B.
