摘要
The nucleus Ti-46 has been studied with the reaction Mg-24(Si-28,alpha2p)Ti-46, at the bombarding energy of 115 MeV. Thin target foils backed either with Au or Pb layers were used in order to perform DSAM lifetime measurements. The yrast 13(-), 14(-), and 15(-) levels were found to depopulate towards a sideband with enhanced stretched M1 transitions. The deduced B(E2) and B(M1) rates for the bands with K=0(+) and 3(-) agree in general with the values predicted by the Large Scale Shell Model. As a complementary information, the lifetimes of the yrast 4(+) states in Cr-48 and Cr-50 have been measured in the reactions Mg-24(Si-28,2p2n)Cr-48 and Mg-26(Si-28,2p2n)Cr-50 and found to agree with Shell Model predictions.
