Abstract: Experimental studies on in-beam γ-ray spectroscopy using a <superscript>12</superscript>Be radioactive beam are presented. Inelastic scattering of the neutron-rich <superscript>12</superscript>Be nucleus on <superscript>208</superscript>Pb, <superscript>12</superscript>C, and (CH<subscript>2</subscript>)<subscript>n</subscript> targets has been studied by measuring de-excitation γ-rays in coincidence with scattered particles. The level schemes and transition probabilities are determined for low-lying excited states in <superscript>12</superscript>Be. The present paper presents a brief review of the spectroscopic results, which may be associated with the N = 8 shell quenching near the drip line. [ABSTRACT FROM AUTHOR]
