Scattering of low-energy electrons by polar molecules: An analytic approach
(American Physical Society, 1998)
The scattering of low-energy electrons by polar molecules is considered. The excitation to the rotational states in the sudden approximation and the effect of the Coulomb dipole force to all orders are taken into account. ...

Coulomb breakup in a transformed harmonic oscillator basis
(American Physical Society, 2006-05-10)
The problem of Coulomb breakup in the scattering of a two-body loosely bound projectile by a heavy target is addressed. A basis of transformed harmonic oscillator (THO) wave functions is used to discretize the projectile ...

Analytical transformed harmonic oscillator basis for continuum discretized coupled channels calculations
(The American Physical Society, 2009)
A new method for continuum discretization in continuum-discretized coupled-channels calculations is proposed. The method is based on an analytic local-scale transformation of the harmonic-oscillator wave functions proposed ...

Continuum coupling in one-dimensional scattering using a transformed harmonic oscillator basis
(American Physical Society, 2002)
The continuum coupling in a one-dimensional scattering problem was studied within a semiclassical approach by means of a transformed harmonic oscillator (THO). The THO basis provided a finite set of normalized states ...

Coupling to breakup channels using a transformed harmonic oscillator basis
(American Physical Society, 2002-01-01)
The application of a recently proposed procedure for discretizing the continuum to collision processes involving weakly bound nuclei is studied. In particular, the coupling to breakup states in ...

Continuum discretization in a basis of transformed harmonic-oscillator states
(American Physical Society, 2001)
The method of defining a transformed harmonic-oscillator (THO) basis, designed to take an account of continuum, by an appropriate discretization is discussed. This method is applied to two analytical one-dimensional ...

Configuration localized wave functions: General formalism and applications to vibrational spectroscopy of diatomic molecules
(American Physical Society, 2000)
A general formalism for constructing configuration localized states for one-dimensional potentials is presented. It allows the evaluation of accurate approximations to the vibrational matrix elements of the momentum operator ...

Continuum discretization using orthogonal polynomials
(American Physical Society, 2003)
A method for discretizing the continuum by using a transformed harmonic oscillator basis has recently been presented [Phys. Rev. A 63, 052111 (2001)]. In the present paper, we propose a generalization of that formalism ...
