FULL PF SHELL STUDY OF A=47 AND A=49 NUCLEI

Complete diagonalizations in the pf major shell lead to very good agre ement with the experimental data (level schemes, transitions rates, an d static moments) for the A=47 and A=49 isotopes of Ca, Sc, Ti, V, Cr, and Mn. Gamow-Teller and M1 strength functions are calculated. The ne cessary monopole modifications to the realistic interactions are shown to be critically tested by the spectroscopic factors for one particle transfer from Ca-48, reproduced in detail by the calculations. The co llective behavior of Ti-47, and of the mirror pairs V-47-Cr-47,and Cr- 49-Mn-49 is found to follow at low spins the particle plus rotor model . It is then analyzed in terms of the approximate quasi-SU(3) symmetry , for which some new results are given.
