    "abstract": "The integrability of one dimensional quantum mechanical many-body problems\nwith general contact interactions is extensively studied. It is shown that\nbesides the pure (repulsive or attractive) $\\delta$-function interaction there\nis another singular point interactions which gives rise to a new one-parameter\nfamily of integrable quantum mechanical many-body systems. The bound states and\nscattering matrices are calculated for both bosonic and fermionic statistics.",
