“…A number of methods have been suggested for the calculation of these two nucleon transfer form factors, but to our knowledge only two of them [3, 41, which use expansions on a complete set of functions, can, by carrying the expansion sufficiently far, approximate the asymptotic part of the form factor sufficiently well. In the first of these methods the basis states are of harmonic oscillator type [ 3 ] , in the other they are Sturm-Liouville functions [4]. It should be noted that although the method of [3] in principle must lead to the correct result, in realistic calculations it implies the diagonalization of matrices of extremely high rank (of the order of lOOO), i.e., the convergence of the expansion is slow.…”
