Analysis of theC12(p→, 

Modifications of the tensor and spin-orbit interactions and the stretched states inPb208

“…Some of the consequences of this m ' scaling are (1) modifications of the strength and geometry of the kaonand nucleon-nucleus optical potentials [15,8]; (2) an enhancement of the NN spin-orbit force and a reduction (at large q) of the tensor interaction in the nuclear medium [8,9]; (3) a stiffening of nucleon-nucleus spin-isospin response [9]; (4} a partial explanation of the Okamoto-Nolen-Schiffer anomaly [16,17], based on the reduction, in medium, of the neutron-proton mass difference [18 -20]; and (5) enhanced kaon production in relativistic heavy-ion collisions [21]. The first two effects are discussed in more detail below.…”

“…In the case of~C, the target investigated in this experiment, the situation is particularly unclear. Neither type of calculation of A&, the analyzing power, for naturalparity states shows good agreement with the data for scattering angles beyond the first minimum [2,4,5]. Two transitions to unnatural-parity states involving spin-fiip have been studied so far at intermediate energies.…”

“…The situation is similar for the 15.11-MeV J,T = 1+,1 state. The nonrelativistic calculation makes predictions similar to the nonexchange relativistic calculation for A&, and these fit the data better than a relativistic calculation with exchange included, although the latter does a better job with the unpolarized differential cross sections [4,5]. Measurements of P -A& (polarization minus analyzing power) for these two states at 400 MeV do not clearly favor either type of model [6].…”

“…Where such electron data did not exist, a length parameter of 1.681 fm consistent with elastic electron scattering data has been adopted. The transition matrix elements and the oscillator parameters, corrected for center-of-mass efFects as described by Comfort et al [2], are given in Table II Since the phase shifts do not vary rapidly with energy, it is not expected that these differences significantly afFect the results. Some calculations were also done with parameter sets determined at different energies, and the changes observed were generally small.…”

“…It brings in the possibility of strong coupled channels effects for collective states as well as the need for a very large shell-model space to span all the contributing con6gurations. Comfort et al and published previously [2], all the data were taken with the High Resolution Spectrometer (HRS) at LAMPF. The 800-MeV data were taken by a slightly different group, and most have been published previously [3 -5].…”
