标题： The dependence of the nuclear charge form factor on short range correlations and surface fluctuation effects

摘要： 我们研究了核表面涨落对轻核谐振子弹性电荷形式因子的影响，同时通过Jastrow相关因子近似处理短程相关性。 在此描述中，通过在两体部分截断集团展开式来包含表面涨落效应，发现这在一定程度上改善了对$^{16}O$和$^{40}Ca$的弹性电荷形式因子的拟合。 然而，预计集团展开式的收敛性会变差。 另一个发现是，表面涨落相关性导致点质子形式因子的渐近行为发生剧烈变化，现在在动量转移$q$的大值下，其衰减相当缓慢（即为$const. \cdot q^{-4}$）。 显示英文摘要

摘要： We investigate the effects of fluctuations of the nuclear surface on the harmonic oscillator elastic charge form factor of light nuclei, while simultaneously approximating the short-range correlations through a Jastrow correlation ~factor. Inclusion of surface-fluctuation effects within this description, by truncating the cluster expansion at the two-body part, is found to improve somewhat the fit to the elastic charge form-factor of $^{16}O$ and $^{40}Ca$. However, the convergence of the cluster expansion is expected to deteriorate. An additional finding is that the surface-fluctuation correlations produce a drastic change in the asymptotic behavior of the point-proton form factor, which now falls off quite slowly (i.e. as $const. \cdot q^{-4}$) at large values of the momentum transfer $q$.
