Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

In a series of papers Tan have shown that for zero range interaction many important properties of the system are related to a new state variable, the contact, that describes the probability of finding a correlated particle pair. In this talk, we shall define the general nuclear contact matrices, taking into consideration all partial waves and finite-range interactions, extending Tan's work to nuclear physics. The properties of these matrices will be discussed and the following relations will be presented:
(a) The high-energy photoabsorption cross-section, in the quasi-deuteron regime, is related to the nuclear contacts.
(b) Relations between the contacts and one-nucleon and two-nucleon momentum distributions.
(c) A new asymptotic connection between these distributions.
Using experimental and numerical data we evaluate the value of leading nuclear contacts.
