The $^{130}$Sn(d,p)$^{131}$Sn Reaction in Inverse Kinematics

The r-process is thought to be responsible for the synthesis of about half of the nuclear species heavier than Fe, but little experimental information is available for nuclear structure and the r-process near the N=82 closed neutron shell and the A$\sim$130 abundance peak. We have acquired (d,p) reaction data on $^{130}$Sn and $^{132}$Sn$^1$ in inverse kinematics using 630 MeV beams (4.85 MeV/u for $^{130}$Sn) and a CD$_2$ target of effective thickness $\simeq$160 $\mu$g/cm$^2$. An array of 20 Si strip detectors was used to detect reaction products in the range $\theta_{lab}\simeq$67$^{\circ}$-167$^{\circ}$. The $^2$H($^{130}$Te,p)$^{131}$Te reaction was used for calibration purposes. More experimental details and a status report on the analysis will be presented. \\ \\ $^1$K. L.
