Van der Waals repulsive peaks in four bodies.

Van der Waals interactions can be used to create molecules. Recently, it is observed that van der Waals interactions can be repulsive. In this presentation, The repulsive peaks within four-body van der Waals coupled states will be investigated. Specifically, nsnsns(n$+$9)s will be studied. The principle quantum number n dependence will be presented. It is shown that the peak size increases as the energy difference between two coupled states increases.
