Survey of (p,t) Reactions in the1pShell

A comprehensive survey of 21 ($p,t$) reactions for a wide range of $1p$-shell nuclei is made using zero-range distorted-wave Born-approximation codes and previously calculated two-particle fractional parentage coefficients. Average optical parameters are used for the proton and triton potentials in an attempt to relate magnitudes of transitions in different nuclei. A reasonable fit is obtained to the experimental data, but there remain discrepancies in strong transitions for target nuclei with $A>~14$. An effect of ($2s-1d$) admixture which acts differently in $L=0\mathrm{}$ and $L=2\mathrm{}$ transfer is proposed as a likely explanation of this difficulty.
