50Cr(p, g)51Mn Reaction from Ep = 1·45 to 2·07 MeV

The Reaction Np ! Pp ? from Threshold up to 570 Mev

The reaction np ! pp ? has been studied in a kinematically complete measurement with a large acceptance time-of-ight spectrometer for incident neutron energies between threshold and 570 MeV. The proton-proton invariant mass distributions show a strong enhancement due to the pp(1 S0) nal state interaction. A large anisotropy was found in the pion angular distributions in contrast to the reaction...

REACTION AT 198 MeV

The reaction 45Sc(n, P)45Ca has been studied at an energy of 198 MeV with energy resolution of about 1 MeV. Measurements were carried out at nominal angles 0°, 3°, 6®, 9®, 12°, 15°, 18" and spectra obtained up to -40 MeV excitation energy in 45Ca . Significant Gamow-Teller strength is observed at an excitation energy of about 7 MeV, somewhat higher than predicted by shell-model calculations . T...

MEASUREMENTS OF INPLANE POLARIZATION TRANSFER COEFFICIENT IN 24Mg(p,p') REACTION AT Ep=65 MeV

57%o REACTIONS AT EP = 120 MeV

Differential cross sections for the (p, n) reaction on ‘*,%r and 57,5XFe have been measured for angles up to Slirh = X0.5” and 14.6”, respectively, using 120 MeV protons. The observed angular distributions are used to evaluate the location and strength of Gamow-Teller resonances. A shell-model calculation of this strength distribution is presented and compared with the experimental results. The...
