High-resolution studies of beta-delayed proton emitters at IGISOL facility.

Beta-decays ofAl andTi have been studied by applying ion guide techniques, gamma detection and a gas-Si telescope for charged-particle detection. The experimental beta-decay strength ofTi was found to be quenched by a factor of q = 0.64 compared to our shell model calculations below 8 MeV excitation energy inSc. This result is in line with the generally accepted value of q = 0.77. The isobaric analogue state of theTi ground state was measured to contain 10(8)% isospin impurity. This relatively high value could be well reproduced by the shell model calculation in the sdfp space. Gamma-decay of the T = 3/2 isobaric analogue state inMg was observed together with its decay by proton emission. The resonance strength from the ground state ofNa to the isobaric analogue state inMg was determined as 5.4(17) meV. The experimental proton width, 13(4) meV, agrees with the calculated value of 21 meV. [ABSTRACT FROM AUTHOR]
