This contribution was of the order of 1/300 at the maximum of the excitation function and 1/50 at about Ep=40 MeV. */ RCT=209BI(P,GAMMA)210PO; /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,1; INC-ENGY-LAB=52MEV; SYS-ERR=(9%'6',3%'7',5%'8',3%'9'); /* '6' Counting efficiency */ /* '7' Chemical yield */ /* '8' Beam monitoring */ /* '9' Target weighting */ /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; INC-ENGY-LAB SIGMA DELTA-SIGMA (MEV) (UB) (UB) 1.127E+01 2.581E+02 +-3.261E+01 1.214E+01 3.833E+02 +-4.191E+01 1.310E+01 3.191E+02 +-4.300E+01 1.510E+01 2.298E+02 +-2.710E+01 1.745E+01 1.771E+02 +-2.238E+01 1.849E+01 1.503E+02 +-1.644E+01 2.006E+01 1.181E+02 +-1.492E+01 2.345E+01 9.014E+01 +-1.510E+01 2.554E+01 8.590E+01 +-1.370E+01 2.928E+01 7.577E+01 +-9.575E+00 3.120E+01 6.748E+01 +-7.956E+00 3.329E+01 6.369E+01 +-6.964E+00 3.494E+01 5.511E+01 +-9.231E+00 3.729E+01 6.619E+01 +-1.001E+01 3.938E+01 5.302E+01 +-8.454E+00 4.164E+01 6.011E+01 +-7.086E+00 4.329E+01 5.618E+01 +-6.897E+00 4.590E+01 4.086E+01 +-5.910E+00 4.756E+01 5.618E+01 +-6.897E+00 5.043E+01 4.371E+01 +-5.842E+00 \END; /*===================================================================*/ |
