Program in C for studying characteristic properties of two-body interactions in the framework of spectral distribution theory

Abstract We present a program in C that employs spectral distribution theory for studies of characteristic properties of a many-particle quantum-mechanical system and the underlying few-body interaction. In particular, the program focuses on two-body nuclear interactions given in a J T -coupled harmonic oscillator basis and calculates correlation coefficients, a measure of similarity of any two interactions, as well as Hilbert–Schmidt norms specifying interaction strengths. An important feature of ... Title of program: sdt Catalogue Id: AEQG_v1_0 Nature of problem The program calculates second-order energy moments, such as variances and correlation coefficients, widely used as measures of the overall strength of an interaction and its similarity to other interactions. It allows for studies of the physical properties of various interactions and their effect on many-particle systems.
