Entrance and exit D517800100013 windows for the beam and for the reaction products D517800100014 were fabricated from 2-mu-m nickel foil or 8-mu-m D517800100015 aluminum foil. The target was filled with gaseous 3He D517800100016 (98% enrichment) to a pressure of 200 Torr. D517800100017 DETECTOR (TELES,SI,SI) Silicon semiconductor telescopes (the D517800100018 thickness of the deltaE spectrometer was 50 mu-m, and D517800100019 that of the E spectrometer could be varied to 4 mm). D517800100020 Collimation for the telescopes was provided by a D517800100021 system of rectangular slits, which set the aperture D517800100022 angle at +-0.4 degree. The energy resolution of the D517800100023 telescope for the deuterons was about 140 keV. D517800100024 ERR-ANALYS No information on uncertainties D517800100025 ANALYSIS For determining the positions of the 5Li levels, the D517800100026 energy of the beam alpha particles at the center of D517800100027 the gaseous target was found experimentally within l% D517800100028 by comparing the kinematic curves Ep(theta) for the D517800100029 reactions 3He(alpha,p)6Li and 1H(alpha,p) , which D517800100030 were detected simultaneously with deuterons in the D517800100031 experiment. D517800100032 ADD-RES (STRUC) The 5Li ground state lies at E=1.93+-0.21 MeV D517800100033 and has a half-width 1.9+-0.25 MeV in the c.m. frame D517800100034 of the 4He+p pair; the first excited state of the D517800100035 nucleus 5Li lies at E=4.74+-0.22 MeV in the c.m. D517800100036 frame of the 4He+p pair. This position corresponds to D517800100037 an excitation energy E=2.82+-0.35 MeV in the 5Li D517800100038 nucleus with a half-width 1.64+-0.25 MeV.
