A Shell Model Calculation for Scattering of Electrons by Be9
Physical Research Laboratory, Ahmedabad-9, India
(Received January 28, 1961)
Elastic and inelastic scattering of 190 Mev electrons by ground and 2.43 Mev states of Be9 is computed by using an intermediate coupling shell model. The discrepancy between the calculated and the observed inelastic cross sections reported earlier is now removed by taking the correct spin value J=5/2- for the 2.43 Mev state. It is shown that a good fit to the observed data requires that different radial extension parameters be chosen for the s- and p-shell nucleons. The best values obtained are a0=1.23 f for the s-shell and 2.0 f for the p-shell.
