    "abstract": "We investigate the shell structure of spherical nuclear bubbles in simple\nphenomenological shell model potentials. The shell correction energies for\ndoubly magic bubbles may be as large as -40 MeV and probably imply a very long\nlifetime against spontaneous fission. Beta-stability occurs for ratios of the\nneutron number N to the proton number Z which differ markable from the\nbeta-stability valley of ordinary compact nuclei. The alpha-decay probability\nis shown to be very small for proton rich bubbles with a moderately large outer\nradius. Metastable islands of nuclear bubbles are shown to exist for nucleon in\nthe range A=450 - 3000.",
