    "abstract": "An extended pairing plus QQ force model, which has been shown to successfully\nexplain the nuclear binding energy and related quantities such as the symmetry\nenergy, is applied to study the alpha-like four-nucleon correlations in\n1f_{7/2} shell nuclei.\n  The double difference of binding energies, which displays a characteristic\nbehavior at $N \\approx Z$, is interpreted in terms of the alpha-like\ncorrelations. Important roles of proton-neutron interactions forming the\nalpha-like correlated structure are discussed.",
