A new SPEG mass measurement experiment has been performed to determine masses closer to the neutron drip-line in the mass region .Lambda.~ 10-50.The precision of 37 masscs has been improved and 8 masses were measured for the first time. The region covered was motivated by the study of shell structure and of shape coexistence in the region of closed shells N = 20 and N = 28. The evolution of the two neutron separation energies and the shell correction energy have been studied as a function of the neutron number. The results thus obtained provide a means of identifying, in exotic nuclei, new nuclear structure mei, new nuclear structure effects that are well illustrated by the changes of the conventional magic structure.

Měřeny hmotnosti jader v oblasti .Lambda. ~ 10-50. U 8 jader byla hmotnost změřena poprvé.
