    "abstract": "Proton-neutron (p-n) interactions and its various aspects in $N\\approx Z$\nnuclei of $g_{9/2}$- and $f_{7/2}$ subshell are studied using a schematic model\ninteraction with four force parameters proposed recently. It is shown that the\nmodel interaction well reproduces observed physical quantities: the double\ndifferences of binding energies, symmetry energy, Wigner energy, odd-even mass\ndifference and separation energy, which testifies the reliability of the model\ninteraction and its p-n interactions.\n  First of all, the double differences of binding energies are used for probing\nthe p-n interactions. The analysis reveals different contributions of the\nisoscalar and isovector p-n pairing interactions to two types of double\ndifference of binding energies, and also indicates the importance of a unique\nform of isoscalar p-n pairing force with all $J$ components. Next, it is shown\nthat this p-n force is closely related to the symmetry energy and the Wigner\nenergy. Other calculations demonstrate significant roles of p-n interactions in\nthe odd-even mass difference and in the separation energy at $N=Z$.",
