In fact, the interest never ceased, as some authors have found in this method an effective way of handling the continuous spectrum of scattering operators, in addition to other operators. The motivation behind the introduction of the J-matrix method will be presented in brief. The introduction of fast computing machines enabled theorists to perform cal- lations, although approximate, in a conveniently short period of time. This made it possible to study varied scenarios and models, and the effects that different possible parameters have on the ?nal results of such calculations. The ?rst area of research that bene?ted from this opportunity was the structural calculation of atomic and nuclear systems. The Hamiltonian element of the system was set up as a matrix in a convenient, ?nite, bound-state-like basis. A matrix of larger size resulted in a better con?guration interaction matrix that was subsequently diagonalized. The discrete energy eigenvalues thus obtained approximated the spectrum of the system, while the eigenfunctions approximated the wave function of the resu | | 出版日期 | Book 2008 | | 关键词 | J-matrix method; Matrix; Potential; atomic collision; cluster; nuclear physics; numerical regularization; q | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4020-6073-1 | | isbn_softcover | 978-90-481-7527-7 | | isbn_ebook | 978-1-4020-6073-1 | | copyright | Springer Science+Business Media B.V. 2008 |
