    "abstract": "We show how the scattering phase shift, the s-wave scattering length and the\np-wave scattering volume can be obtained from Riccati equations derived in\nvariable phase theory. We find general expressions that provide upper and lower\nbounds for the scattering length and the scattering volume. We show how, in the\nframework of the variable phase method, Levinson\u0027s theorem yields the number of\nbound states supported by a potential. We report new results from a study of\nthe heteronuclear alkali dimers NaRb and LiRb. We consider $ab$ $initio$\nmolecular potentials for the X${}^1\\Sigma^+$ and $a{}^3\\Sigma^+$ states of both\ndimers and compare and discuss results obtained from experimentally based\nX${}^1\\Sigma^+$ and $a{}^3\\Sigma^+$ potentials of NaRb. We explore the mass\ndependence of the scattering data by considering all isotopomers and we\ncalculate the numbers of bound states supported by the molecular potentials for\neach isotopomer.",
