Excitation functions of the /sup 28/Si (d,p/sub 0/), (d,p/sub 1/), (d,p/sub 2/), (d,p/sub 3/), and (d,p/sub 4/) reactions have been measured from E/sub d/ = 1.0 to 2.5 MeV at theta/sub L/ = 15/sup 0/, 30/sup 0/, 40/sup 0/, 50/sup 0/, 60/sup 0/, 70/sup 0/, 90/sup 0/, 120/sup 0/, 135/sup 0/, and 155/sup 0/ (in steps of 10 keV). Angular distributions of the p/sub 0/-p/sub 4/ groups at E/sub d/ = 1.57, 1.82, 1.99 and 2.35 MeV have been measured in the angular region 15/sup 0/--155/sup 0/ (in steps of 10/sup 0/--15/sup 0/). By using these angular distributions, the excitation functions were normalized. In addition, excitation functions of the /sup 28/Si (d,p/sub 18/) /sup 29/Si/sub 18th/(E/sub x/ = 6.38 MeV) have been measured from E/sub d/ = 1.5 to 2.5 MeV at theta/sub L/ = 40/sup 0/, 50/sup 0/, 70/sup 0/, 90/sup 0/, 120/sup 0/, 135/sup 0/, and 155/sup 0/ (in steps of 10--20 keV) by means of a charged particle spectrometer consists of a semiconductor detector with a small magnetic analyzer. Angular distributions of the /sup 28/Si (d,p/sub 18/) /sup 29/Si/sub 18th/ at E/sub d/ = 1.85, 1.87, 2.00, and 2.09 MeV have been measured in the angular region 40/sup 0/-150/sup 0/ (in steps of 10/sup 0/--15/sup 0/). Absolute differential cross sections of all channels have been obtained in terms of comparison with Rutherford scattering cross section. We observed a new intermediate resonance on the excitation functions at E/sub d/ = 1.90 MeV. In addition, we observed two other intermediate resonances at E/sub d/ = 2.12 MeV and 2.33 MeV. These resonances were identified by using certain experimental criteria of intermediate resonance in nuclear reaction. Spins and parities of these intermediate resonances were obtained as 2/sup +/(1.90 MeV resonance), 2/sup +/(2.12 MeV resonance), and 3/sup +/ (2.33 MeV resonance), respectively.
