The gold layered backing used for this A0428001 20 purpose was especially developed for long term A0428001 21 experiments and high beam power of up to 10 KW/cm2. A0428001 22 The depletion in respect to the detrimental 13-C was A0428001 23 improved by a factor of 1000. The target was replaced A0428001 24 when a deterioration of about 20% was found. A0428001 25 METHOD (BCINT,EXTB,GSPEC) A0428001 26 DETECTOR (HPGE) An array of three or four large detectors in A0428001 27 close geometry, actively shielded with bismuth A0428001 28 germanate crystals. A0428001 29 (BGO) The crystals were used for active shielding and A0428001 30 anti-Compton detectors. A0428001 31 The whole detector setup was placed on a heavy A0428001 32 motor-driven revolving table. A0428001 33 ADD-RES The S(E1) and S(E2) factors deduced from the gamma A0428001 34 angular distributions have been extrapolated to the A0428001 35 range of helium burning temperatures applying the A0428001 36 R-Matrix method, which yielded A0428001 37 S(E1)/300 = (76 +/-20) keV*b and A0428001 38 S(E2)/300 = =(85 +/- 30) keV*b.

A0428002 4 ANALYSIS (INTAD) The values for Sigma(E1), Sigma(E2)/Sigma(E1), A0428002 5 and Sigma(E2) have been obtained by using the formula A0428002 6 for the interference of E1 and E2 transitions in A0428002 7 angular distributions, given in the paper of Dyer and A0428002 8 barnes. The parameter (PHASE) of this formula was not A0428002 9 kept open, but determined by using the elastic alpha - A0428002 10 scattering data of Plaga and D'Agostino Bruno.
