C307900100024 INC-SPECT 32Si beam, a long-lived radioisotope, had an C307900100025 intensity of approximately 10**5 particles per second C307900100026 and a beam purity of ~90% due to a 32S contaminant. C307900100027 DETECTOR (MAGSP,SI,TELES) The SOLARIS solenoidal spectrometer C307900100028 with a magnetic field of 3 T. HELIOS four-sided array C307900100029 of position-sensitive silicon detectors (PSD). C307900100030 SAMPLE A 120-microg/cm2 (CD2)n target. C307900100031 METHOD (EDE,COINC) Protons produced by reactions of the 32Si C307900100032 beam impinging on (CD2) n target were analyzed by the C307900100033 newly developed SOLARIS solenoidal spectrometer. The C307900100034 energies and positions at which the protons returned C307900100035 to the beam axis were measured using the HELIOS C307900100036 array. The projectile-like Si recoils were uniquely C307900100037 identified from other reaction channels or un-reacted C307900100038 beam components, including the 32S contaminant, by a C307900100039 square (5x5 cm2) Si recoil detector telescope with C307900100040 quadrant segmentation in the dE. A 20-ns timing C307900100041 coincidence between the protons and the Si recoils C307900100042 was applied to select the (d,p) reaction channel, to C307900100043 separate the S contamination and to reduce the C307900100044 background.

C307900300009 For the unbound states, a binding energy of 200 keV C307900300010 for the transferred neutron was assumed in a C307900300011 "quasi-bound" approach.
