Estimate of the location of the neutron drip line for calcium isotopes from an exact Hamiltonian with continuum pair correlations

NUCLEAR STRUCTURE ^{41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73}Ca; calculated binding energies, S(2n), Fermi level and pairing gaps of even Ca isotopes, energies of single-particle bound levels for odd Ca isotopes from A=41-73, occupation probabilities for ^50,54,62,66Ca, for even Ca isotopes, binding energies of ^{51,53,55,57,59,61}Ca; deduced one particle drip line at ⁵⁷Ca, and the two neutron drip line at ⁶⁰Ca or ⁶⁶Ca, depending on the model used. Modified Richardson equations to solve the many-body system, with two isospin independent models, and an isospin dependent model. Comparison with available experimental data.
