“…III, were found to be larger by about a factor of 2. Both neutron and proton radii have a tendency to be larger than those in the analysis at 180 MeV (and in electron scattering) but the discrepancy is considerably less than in the original analysis by Boyer e& O,L [6].…”

“…The data points of Boyer et aL [6] for 7r scattering on 42Ca show a larger spread than seen in the other isotopes, making it impossible to obtain a reasonable value of yũ nder the same conditions as the other cases treated. In an attempt to see if this variation in the value of y2 affected the neutron radius obtained, some modifications of the data were considered.…”

“…Upon reading details presented in Ref. [6) some estimate of realistic errors can be obtained. The author states that, in particular for the forward angles, the data points were found to be reproducible only to the order of 5%%uo.…”

“…The present analysis relies primarily on the pion scattering data of Boyer et aL [6]. While these authors extracted the total neutron radii from their data, we have made a more detailed analysis of this same data using an improved scattering theory and a specific model of the nuclear density to obtain the valenceand core-neutron radii independently.…”

We have analyzed pion scattering data to determine the proton and neutron radii of the calcium isotopes ' ' ' Ca using model densities in which the neutron matter distributions are considered to have two components corresponding to core and valence neutrons. The proton radii determined agree with those obtained by electromagnetic means. The radii of the valence distributions show a monotonic decrease throughout the shell &om 4.9 fm in Ca to 4.4 fm in Ca and 4.2 fm in Ca, although this last case is only indicative. The large valence neutron radius of Ca suggests that the ground state of this nucleus may have some characteristics of a bound dineutron orbiting a closed core.PACS number(s): 21.10.

“…In a recently published analysis [4] J.-P. Dedonder and I applied pion multiple scattering theory to the analysis of pion scattering data by Boyer et aZ. [29] to make a determination of the absolute total neutron radii to an accuracy of the order of 1%, an error about a factor of 3 smaller than any previous determination.…”
