  In beam test experiments have been carried out for particle identification
using digital pulse shape analysis in a 500~$\mu$m thick Neutron Transmutation
Doped (nTD) silicon detector with an indigenously developed FPGA based 12 bit
resolution, 1 GHz sampling digitizer. The nTD Si detector was used in a
low-field injection setup to detect light heavy-ions produced in reactions of
$\sim$ 5 MeV/A $^{7}$Li and $^{12}$C beams on different targets. Pulse height,
rise time and current maximum have been obtained from the digitized charge
output of a high bandwidth charge and current sensitive pre-amplifier. Good
isotopic separation have been achieved using only the digitized charge output
in case of light heavy-ions. The setup can be used for charged particle
spectroscopy in nuclear reactions involving light heavy-ions around the Coulomb
barrier energies.
