Practical Scheme

A method suggested by Elliott for calculating nuclear interaction matrix elements directly from phase shifts is developed into a practical scheme applicable to all partial waves. Matrix elements are constructed from experimental phase shifts and compared to several other calculations. A shell-model calculation of 58Ni based on these matrix elements gives results comparable to those of Kuo.

An approach is outlined wherein the Bethe–Goldstone wave function may be computed in a shell-model basis from a knowledge of the harmonic-oscillator matrix elements. These in turn may be derived from the N–N phase shifts by a number of different methods. The Pauli operator is treated exactly in the space of two-particle shell-model states. The method is applied to a calculation of the levels of 18O and 18F and results obtained using different two-body matrix elements are compared.

Apparent Conflict

A recent shell model calculation has predicted a low-lying! + level in 5He, in apparent conflict with experimental results. We have confirmed the prediction with an alternative shell model interaction chosen specifically to fit properties of light nuclei. The level is expected to be very broad so that it would not be easily seen in reactions. It should contribute significantly to n-a phase shifts, but did not appear in previous analyses because of the small value of about 3 fm chosen for the channel radius a. A ! + level at the expected energy of about 7 MeV is obtained for a ::::: 5�1 fm. Broad ~ + and ~ + levels are then found at about 14 MeV in agreement with the shell model calculations. Properties of the low-lying ~ - and! - levels in 5He and 5Li are discussed, but the measured values now available do not favour a particular value of the channel radius.
