... Abstract Global potential energy surfaces (GPES) for tetratomic molecular systems, containing at least one group of two identical nuclei, which fit ab initio data can be obtained preserving the accuracy of the ab initio points. The permutational symmetry of the potential, corresponding to the two identical nuclei, is treated analytically in this new version of the previous published program GFIT4C (Computer Physics Communications catalogue number: ADNB). The global fit obtained fulfills the stringent ... Title of program: GFIT4C-2 Catalogue Id: ADOV_v1_0 Nature of problem Given a set of ab initio points of a molecular system with N atoms, the problem is to obtain a golbal analytical (3N - 6)-dimensional representation of the corresponding adiabatic potential having all the symmetry properties of the system and satisfying the stringent criteria [1] needed in molecular dynamical calculations. In Part II.1 [4] of this series we have dealt with the tetratomic system class ABCD and six-dimensional (6D) representation (program GFIT4C). In the present Part II.2 we treat ...

... Abstract With the growing popularity of the velocity map imaging technique, a need for the analysis of photoion and photoelectron images arose. Here, a computer program is presented that allows for the analysis of cylindrically symmetric images. It permits the inversion of the projection of the 3D charged particle distribution using the Onion Peeling Algorithm. Further analysis includes the determination of radial and angular distributions, from which velocity distributions and spatial anisotropy para... Title of program: Glass Onion Catalogue Id: ADRY_v1_0 Nature of problem Information about velocity and angular distributions of photofragments is the basis on which the analysis of the photolysis process resides. Reconstructing the three-dimensional distribution from the photofragment image is the first step, further processing involving angular and radial integration of the inverted image to obtain velocity and angular distributions. Provisions have to be made to correct for slight distortions of the image, and to verify the accuracy of the analysis process.

... Title of program: PIPIT Catalogue Id: ABIH_v1_0 Nature of problem Angular distributions for the elastic scattering of pions are generated by summing a partial wave series. The elastic T-matrix elements for each partial wave are obtained by solving a relativistic Lippmann- Schwinger equation in momentum space using a matrix inversion technique. The Coulomb interaction is included essentially exactly using the method of Vincent and Phatak. The piN amplitude is obtained from phase shift information on-shell and incorporates a separable off-shell form factor to en ...

... Abstract A knowledge of nonpertubative propagators is often needed when the standard perturbative methods are not applicable. An example of this is the bound state problem in field theory. While a nonperturbative result is valuable by itself, it is also an important guide for those who work on developing phenomenological models for the nonperturbative problem. The Feynman–Schwinger representation approach provides a convenient framework for calculating nonperturbative propagators. In this paper we pro... Title of program: phi3 Catalogue Id: ADNO_v1_0 Nature of problem The program provided here evaluates the mass and distribution probabilities of the fully interacting n-body propagator (n<=3) for scalar chi-square phi interaction in 3+1 dimensions. The evaluation takes into account all self energy, vertex dressing, and exchange interaction contributions except those involving matter loops (the quenched approximation).

### A C-code for the double folding interaction potential for reactions involving deformed target nuclei

... Abstract We present a C-code designed to obtain the interaction potential between a spherical projectile nucleus and an axial–symmetrical deformed target nucleus and in particular to find the Coulomb barrier, by using the double folding model (DFM). The program calculates the nucleus–nucleus potential as a function of the distance between the centers of mass of colliding nuclei as well as of the angle between the axis of symmetry of the target nucleus and the beam direction. The most important output ... Title of program: DFMDEF Catalogue Id: AENI_v1_0 Nature of problem The code calculates in a semimicroscopic way the bare interaction potential between a spherical nucleus and a deformed but axially symmetric one as a function of the center of mass distance as well as of the angle between the axis of symmetry of the target nucleus and the beam direction. The height and the position of the Coulomb barrier are found. The calculated potential is approximated by a conventional Woods-Saxon profile near the barrier. Dependence of the barrier parameters upon the charac ...

... Title of program: SUBMMW Catalogue Id: ACYC_v1_0 Nature of problem SUBMMW assumes that the energy levels of the lasing molecule are those of a symmetric top. The molecule is pumped by an intense laser source, for example, the P(20) line of carbon dioxide, from a rotational sub- level of one vibrational level to a higher vibrational level and then decays to a lower rotational level within the higher vibrational level emitting sub-millimeter wave radiation. Given the parameters of the pump radiation, the constants associated with the lasing molecule, for example ...
