    "abstract": "Isospin singlet (pn) pairing as well as quartetting in nuclei is expected to\narise near the symmetry line $N=Z$. Empirical values can be deduced from the\nnuclear binding energies applying special filters. Within the local density\napproximation, theoretical estimates for finite nuclei are obtained from\nresults for the condensation energy of asymmetric nuclear matter. It is shown\nthat the isospin singlet condensation energy drops down abruptly for |N-Z|~4\nfor medium nuclei in the region A=40. Furthermore, alpha-like quartetting and\nthe influence of excitations are discussed.",
