Quadrupole collectivity in neutron-rich Fe and Cr isotopes.
Intermediate-energy Coulomb excitation measurements are performed on the N ≥ 40 neutron-rich nuclei (66,68)Fe and (64)Cr. The reduced transition matrix elements providing a direct measure of the quadrupole collectivity B(E2;2(1)(+) → 0(1)(+)) are determined for the first time in (68)Fe(42) and (64)Cr(40) and confirm a previous recoil distance method lifetime measurement in (66)Fe(40). The resul...

متن کاملEnhanced quadrupole collectivity at N = 40: the case of neutron-rich Fe isotopes.
The transition rates for the 2(1)+ states in (62,64,66)Fe were studied using the recoil distance Doppler-shift technique applied to projectile Coulomb excitation reactions. The deduced E2 strengths illustrate the enhanced collectivity of the neutron-rich Fe isotopes up to N = 40. The results are interpreted using the generalized concept of valence proton symmetry which describes the evolution o...
متن کاملProduction of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying
In this research, the production of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying was investigated and evaluated. Ferrotitanium (containing 70%Ti), titanium and graphite were used as the raw materials. Initial mixtures were milled in different time durations under the pure nitrogen atmosphere with the pressure of 5atm. The results showed that when N2 pressure is 5 at...
متن کاملStructure of 52 , 54 Ti and shell closures in neutron - rich nuclei above 48 Ca
The level structure of 54 22Ti32 has been explored for the first time by combining β-decay measurements from fragmentation products with prompt γ -ray spectroscopy following deep inelastic reactions. The latter technique was also instrumental in tracing Ti30 to higher spin. The data provide new tests of effective interactions for full pf -shell calculations in neutron-rich nuclei above 48Ca. Th...
