Structure of 16C from analyses of proton scattering data and the B(E2) problem

Abstract

The B(E2) value for the decay of the 2+_1 state in 16C to ground has been the subject of much discussion. Analyses assuming a simple model of two neutrons coupled to a 14C core of the available data, which extend over an order of magnitude,gives reasonable agreement but with an inclusion of a large effective charge for the neutrons. To assess this situation, a large scale (2+4)hw shell model calculation of 16C has been made from which the wave functions have been used to obtain the B(E2) value. As a check, comparison is made with available data on the spectrum of 16C and intermediate-energy elastic proton scattering.
