s (K+ 12C). Experimental
data for stot: black squares - from
Ref. 82; white squares - from Ref. 83; x- from Ref. 43; for sr
: o - from Ref. 83. The upper solid and dashed curves are for stot,
and the lower ones for sr. (b) stot(K+d)

form factor, and the dot-dash curve is with the Hulthen form factor for

from Ref. 85.

12. Total cross sections for the K+ 12C and
K+ d interactions and the quantity R=stot(K+
12C))/6stot(K+d)
in the region of initial kaon laboratory momenta 350-950 MeV/c [(a)-(c),
respectively]. For (b) the notation is the same as in Fig. 11a; for (c)
it is the same as in Fig. 11b, the white squares are experimental data,
and the dot-dash curve is obtained using a deuteron density in the Gaussian
form. The curves in (a) are obtained using the solid curve in (b) and the
corresponding curves in (c); the dashed curve in (a) is obtained from the
dashed curve in (b) and the solid curve in (c). The points ·
in (a) are the experimental data of Ref. 84, and the black squares are
the data of Ref. 82.

13. Differential cross sections for elastic K+ d scattering
at initial kaon laboratory momenta 0.6 and 0.9 GeV/c (numbers near the
curves). The curves are the calculations (as in Fig. 12c); experimental
data: · - Ref. 80; o - Ref. 62; black squares
- Ref. 81. The dashed curve in the uppeer graph at momentum 0.64 GeV/c and
the solid curve at 0.587 GeV/c demonstrate the change in the calculation
with energy for the extreme values of the momenta at which the experimental
data have been taken.

at initial kaon laboratory momentum 0.8 GeV/c. The notation is the same
as in Fig. 3.

15. Dependence of D E on the initial energy
of the particles. The solid curve is for p12C, the dot
- dash curve for p4Hee, the dashed curve for pd,
and the dotted curve for K+ 12C. The points
o show the values of D E for p+,-
12C at the energies at which they are the same for p-
and p+, and the points ·
and white squares, respectively, show the values when they are different.
