摘要：
The shell evolution of even-even drip line argon isotopes 46-54Ar has been investigated via the shell model calculations using SDPF-U and SDPF-NR two-body effective interactions in two different shell model spaces pi(sd) - nu(fp) and pi(sd) - nu(f(7/2p)). In this work, the energy of first 2+, reduced transition probability B(E2), excitation energy levels as well as how the proton shells evolve with N have been studied. Excellent agreements were obtained for the first 2(+) level along the investigated isotopes within pi(sd) - nu(fp) and pi(sd) - nu(f(7/2p)) model spaces.
